Lower end coins always sell for way too much money at estate auctions in my area. There are a couple of older "collectors' that attend most of them and drive the prices sky high and win most of the items for several multiples of retail. They mostly don't care about condition or problem coins. Local auctioneers love this and have been advertising for coin consignments lately. If I was smart I'd consign some of my beginner mistakes. Auction fever and coins are a potent mix although I've gotten a few deals over the years at auction.
