Terrible,terrible, terrible. Stay away from Bruce Duncan. He is a con artist and deserves a negative infinity amount of stars as possible. A crook, thief and liar by definition. I paid him in advance to appraise some very historical books. Which after through legal and expert advise, I was advised to report him to the Better Business Bureau and have no further dealings with him. I am completely disgusted with this so called "Association." I decided to conduct my own investigation, and I saw on his webpage that it was very clearly noted that "they" do not provide such services, in other words books. I have tried reaching out in a very professional and respectful manner to obtain a refund. He refuses to acknowledge to have ever even met me. However, Bruce has answered phone calls from my colleagues and was happy to assist them within the same day. When they expressed to him that they were calling on my behalf, he threatened to call police and denied that we had even met. He refuses to take my calls, texts, and does not operate through email as the last reviewer describes. He conducts his fraudulent business out of his home (mansion) in Northbrook, Illinois. He asked me to meet him there, and stated that he has a 17 person staff. He told me my appraisal would be ready in two weeks. When i met him there to show him my items, he very adamantly requested I pay him cash and he would have my appraisal and authentication ready in one week or less. This man is a fraud, and my hope is that no one ever trusts him. This man, or business, or whatever his webpage claims to be is not to be dealt with. HEED my warning!! read more
