Don't waste your time. I noticed an ebay sale of a coin and asked for the tracking number. The seller gave it to me and after seeing that it was activated, explained it to them. His ebay id and caching id (yes, he was a geocacher) were close enough that I was able to see that he logged a cache, but didn't log the coin retrieve. I offered to pay for shipping, then to buy it, but he refused. I found the coin owner who also got involved, but neither ebay nor GC.com would do anything about it. The owner marked the coin page as stolen, but that was all she could do.
