My father dabbled in coins and left a very small collection that we had no idea how to value upon his passing. I found ABC GT Coins on Yelp and was impressed by the consistent high reviews left by previous clients, so I called to ask for an assessment. Gary Tanaka answered my call and requested photos so he could get an idea of the scope. i sent photos and later that same day, he called back and we set up an appointment to meet the following day. Talk about timely follow-up! Gary arrived at the appointed time. He sorted the coins and explained to me which had value and why. I was expecting a pure transactional appointment and was so pleasantly surprised that instead, I spent time talking story and having a real conversation with him. I know folks are busy but Gary did not rush, did not pressure, did not undermine the value of my dad's coins. I did sell the coins to him and felt I received a fair and reasonable amount. Much more that the the value of the coins was the value of the time, level of service and overall Aloha that I received from Gary. What a lovely gentleman!!! If ever I have a need within his scope of expertise, I would gladly and unhesitatingly call on him again! A huge Mahalo, Gary, for your Aloha and for sharing your kuleana. You go beyond 5 stars in my book! read more

Great service, personable, reputable! Buy and sell gold and silver. Recommend highly!

Gary was informative and easy to work with. He explained how my coins were valued and gave me a fair price for them. I would recommend him to anyone looking to sell their coins. read more

Gary is who you go to. In fact I will probably only do business with him moving forward. I was a little hesitant meeting up with him for an appraisal, instead of inside a business, but I'm glad I did. He is the most knowledgeable and generous man in the business. Probably one of the few fair guys I've worked on the island. If you're reading reviews to see who is absolutely trustworthy, you can stop now because it's this guy. read more

Gary is a true professional. The entire transaction was excellent. He's very responsive and informative. Will happily use the services again if I ever need them. read more

Gary was very very knowledgeable and thorough while dealing with our transaction. He really took the time to explain everything he was doing in detail and handled all of the items I gave him with care. It meant a lot to me since this was my mother's coin collection. read more

Gary is great to work with, very prompt and courteous. He's extremely knowledgeable, answered all my questions, pointing out what to look out for on coins. He gave me a fair valuation and offer, with which I was extremely pleased. Gary's a great guy, a pleasure to deal with! All in all, a great experience, and I would not hesitate to recommend him to anyone looking to buy or sell coins! read more

Gary is very knowledgeable and trustworthy. He came on time, checked what I had, and gave me what we agreed on. He also offered good prices compared to the other pawn shops I contacted that day. I highly recommend him! Mahalo Nui Gary. read more

Gary is professional, prompt, courteous. He met me at my parents' condo after a brief conversation about some silver (90%) currency that I had to sell. Gary was more than willing to teach me about what to look for in the coins, including checking for key dates, composition, and other things to look for as a collector. While I was not urgently trying to sell, Gary is the only buyer we considered as pricing was fair and the process was easy. read more

I found some silver $1-coins in my father house which he collected for many years. He passed away several years ago. I decided to see if it was worth anything. Called ABC Coins since they had a high rating on YELP. Talk to the owner Gary, he told me to take a picture and send it to him, which I did. I had 85 coins. He called me back and offered me $20- per coin. I was shock. Meet Gary at a location of our choosing. He paid me $1700- cash for the coins. He was very professional and his customer service was excellent. So, if any of you have any old coins laying around give Gary a called. Aloha, Derek....p.s. went to dinner after..ha,ha... read more

See all

Dude, had no idea what to do with these boxes of coins that an uncle left us. Checked around, tried to do research. Finally just gave Gary a call. He returned the call, we went back and forth over some sample coins and he seemed very fair so I met with him to show him what I had. He made it easy -- very flexible with location and time. He shared his knowledge as he went through the stuff and gave what I thought was a very fair and reasonable offer. Best part -- he's a nice guy. I had such a great time talking with him. Highly recommend this bruddah. Lance read more

Where do I start? Well... my great grandpa left a bunch of old coins with me after he passed. I didn't know really what it was or how much it was worth. So, I did some research, started looking up coin buyers, and began to call around. What I learned was for silver coins (say a 1964 quarter), buyers will pay a certain amount times the face value. If you have a lot of coins, it's a lot of money! Anyway, I called every single place I could find on Yelp. A lot of them didn't answer, didn't call back, or were just plain rude and short. Gary from ABC called me back so fast! He spent about 40 minutes of his time pretty much teaching me about coin buying. I have a knack for telling who's bullshitting and who's real! I could tell right off that Gary was a genuine person. I was proven right when he paid waaaaaaay more than any other buyers. I trusted him completely!!! And trust me, he's a pretty trusting guy with people as well! I walked away with 1K! And I still had quite a bit left for emergency money time! I really enjoyed this experience and I hope you all do to! He's a great person and a fantastical knowledgeable coin buyer!!!! If I could rate him a million stars on yelp I would! read more

Gary was very helpful and and answered all our questions. Thank you for making this a pleasant, easy and educational process! Highly recommend. read more

I am so very glad that I found Gary and ABC GT Coins. I was worried about being taken advantage of until I met Gary and sat down with him. He was fair and truthful and educational. He took the time to explain what was what and why. He even corrected me when I made a mistake in his favor when I added up the sales sums. He was honest and asked me to re add because he thought I had shorted myself and he was right! I have more coins at another location and I will be calling Gary again. I would whole heartedly recommend him to anyone looking to sell / buy coins. read more

I inherited some old collectible silver coins after my dad passed away and decided to sell some of them. I found Gary through doing a search on Yelp and contacted him. He was quick to respond and we set up a time to meet in a general area since this is more like his hobby. Gary was friendly, courteous, and had alot of knowledge about lots of different types of coins. He was very thorough looking through the coins and even tested them to make sure they were authentic. He offered me a fair price according to market value and am glad that I contacted him. I would recommend reaching out to him if you are considering downsizing or selling your old coins! read more

This was my first meeting with Gary, and he was very personable, and easy to talk to. He explained his process in collecting, buying and selling coins clearly to me; thereby establishing a connection of good faith and trust between us. I felt we made a fair deal. Thank you, Gary! It was an afternoon well spent getting to know you. I will certainly consider you first for any of my future dealings. read more

I cannot express enough how Grateful I am to have found ABC GT Coins while looking for a reputable coin dealers to liquidate some coins from my now deceased Fathers collection . I had phoned a few, and went to see a dealer but something about Gary... At a moments notice, Gary was prompt to respond to my email and call. He's Fair, Honest, Truthful, very knowledgeable and SO easy to talk to! He's a wealth of information and is forthcoming with educating you along the way. I couldn't be more pleased with the service that Gary provides. I highly recommend ABC GT Coins for any and every need you may have relating to this line of business. Thank you Gary for ALL that you've done for our Ohana! read more

Gary was very accommodating and was happy to meet at a location that was easy and convenient for me.

Hope to do business with you again, A+++ read more

Gary is the most professional and fair individual ive had the pleasure of doing business with. Hes honest and authentic which is rare in the industry. 5 stars is not enough read more

It was a nice talk story Session. He was pleasant and polite. We met in front of Teddy's bigger burgers. So, my wife and I just watching YouTube on coins and thought we might have some coins worth checking out. Showed him our coins and they were nothing worth big bucks. So I will be keeping my coins. But it was nice to get to know Gary. We talked about business, real estate and family. If I'm not going to make thousands of dollars off my coins, it's not worth selling to me. I was hoping for a miracle. It would have been nice to have found a penny that is worth a million. LoL! One can hope..... All in all, it was what I needed. I needed someone to shake me out of my dream world. Back to making my millions instead of finding it. read more

Gary was amazing! I called him to sell him some U.S. Mint Gold and Silver Coins. I was trying to resell them on eBay, however, Gary was able to offer a very good deal and meet me right away on short notice. I appreciate that he drove to a convenient public location to complete the sale and arrived early with professional and friendly service. We even had some time to talk story and talk about our businesses, as we are both business owners. Any way, I look forward to dealing with Gary and his company for future transactions and I'd recommend you give him a call! read more

Stumbled onto ABC GT Coins based on great reviews. One of the best precious metal dealers I've ever met! Gary provides excellent customer service and has a wealth of knowledge. I would recommend doing business with Gary over anyone else. -Burke V. read more

Sorry but this establishment doesn't deserve a . Last Saturday I wanted to get my foreign coins to this place to sale. But he didn't advertise his location. So I called him and left a message asking him where is he located. Again he wouldn't give me an address. Only ask me to email him pictures of what I got. I didn't do this because he could use my photos for his own purpose and not consult with me. Again he calls me and only says that he's located around Don Quixote. Again no address given. When I received his call the first time on Saturday. I was already in the process of selling some of my foreign coins to another currency exchange business where I made $121.00. read more

I met with Gary yesterday with a bag full of coins silver dollars half dollars old dimes buffalo nickels etc. and he took quite a few of them....a very nice man he is. He is also very well-versed in real estate and the market trends here in Hawaii and he was very honest to assess what's going on in the market right now. So I would definitely recommend him for coins and real estate to my friends. read more

I guess they're great if you have something they're interested in. They advertise on Craigslist "Paying too much - 49 years of paying the highest prices..." and since stamps was one of the items they listed as buying, I emailed them asking if we could set up a time to meet, to look over some vintage stamps I inherited from my Grandfather. I also asked if he wasn't interested, maybe he could refer me to another stamp collector/dealer, that could help me. He emails back, "can you send some pictures". I oblige, and send pictures.....(crickets) No response. I email back and ask if he received the pictures?...No response. I email again asking if he didn't get the pictures, could he email with another email address (in case the first one didn't work) Nothing....no response at all. I would have been perfectly fine if he had emailed me back saying that he wasn't interested in looking at the stamps, but instead, I got blown off and he didn't bother to respond to my additional emails. So my experience with this guy, was a complete bust! Disappointing and no way to run a business! read more

Gary offers the best prices on the island. He is also very responsive and easy to work with.

This was my first time working with Gary but it was a positive experience overall. Gary met with me at a public location of my choosing. He gave me a very fair price for my coin and even gave me a few coin tips for the future. Very honest and absolutely no pressure felt during the transaction which made it go as smooth as possible. I will definitely come back for future coin transactions! read more

Had some old coins that I wanted to sell and met with Gary and the process was easy and painless. Speaking to Gary was talking to a friend I've known for many years. He gave me a fair price for the coins. Thanks again Gary! read more

Very straight forward and professional. Convenient to work with. Excellent experience ! read more

With the price of gold appreciating, I decided to take some profits by selling some gold coins. I called around to different places to get some ballpark quotes. One place quoted me a spot premium of 9% and another place didn't want to deal in coins and referred me to 2 other places. I called Gary and left a message requesting a quote for my coins. He responded about 10-15 minutes later, asked me a few questions and quoted me what I felt was a very generous offer !! I took his offer and true to his word without any wheeling and dealing, we made the exchange about an hour later when he drove to my place to meet up. This guy is a library of information that's just not limited to coins and will take the time to explain things to you without any condescending tone being the person with much more knowledge. Thanks Gary for the great service and best of all.... great price ! read more
