I've made exactly one sale, all of duplicates. I currently have some more duplicates for sale, but no one wants them! I couldn't even deal any if I tried! (lol) I tried to trade them first, but no one was interested in them then, either. I don't think it counts though if you sell off duplicates....does it? To me that is not dealing as much as getting rid of what you don't need...I actually lost money on the deal as well. The total I charged for the coins, a little for myself (sic) and shipping actually came out to less than it cost to ship them! I have never sold anything that was then part of my permanent collection, in any of my hobbies, and I hope that I never will. Duplicates are fair game though.
Collector.....but I do love selling on eBay and sending my own coins to NGC. I was totally shocked at the end of the year when eBay sent me the year sales report. I sold 891 coins last year......I was shocked!!
