I am not a retailer, but simply a man nearing retirement trying to downsize. I love Ancient Coins and Ancient Jewish Coins and use this opportunity to sell coins where I have purchased a better quality of that type or where I saw a bargain and took advantage of it. I am not an expert by any means, but I am very upset by the problem of counterfeit coins on Ebay. . As a trademark lawyer in my real life, I fight counterfeit goods all the time. If by any chance you see a coin that you think is not authentic, please let me know. Almost all of my coins were acquired from auction houses that warrant that the coin is authentic and if you explain your concern I will take down the coin until I explore the issue with the auction house that sold me the coin and will let you know what I find out. My father was an avid collector of Native Aerican and ethnic art as well as Modern American Art. Check our my blog AncientJewishCoins.blogspot.com. .
