National Treasure Shop
For several years I ran an eBay store called National Treasure Shop, which sold cool coins, Americana, and political memorabilia. At one point it grossed over $250K/year (though I didn’t profit nearly that much). I attended a couple of eBay Live conferences (when they still held those) and earned the rank of super duper power seller.
I still sell things on eBay from time to time, but not as often as I would like. Think in another life I could have been an eBay tycoon.
