I too have been taken by centsles on eBay; I only got refund (minus my shipping and handling costs to return the coin) after escalating to a Paypal claim. I have done a bit of research and noticed that centsles, world_coinz and other users also seem to be in a ring of "positive feedback" to drown out any negatives. Not only are they also NNC and AGS, they are also operating on eBay under many identities. I wrote to centsles at one point, and got an answer from world_coinz in error. The explanation I got was that they were doing inventory for them! I also checked the registry of businesses of Florida (http://www.sunbiz.org/), and it seems that even though NNC's president is published as Robert Johnson (of centsles) in various publications, his name does not officially appear on the business registry. I congratulate all who have contributed info to this thread.
