Don't sell coins (except for 1) and used to sell the common relics as well as a lot of quality button doubles which were easy to part with for the cash. These days things are different, the "junk" isn't even worth the cost to ship, our best producing button sites have dried up and new ones just don't seem to happen, and so far there has not been a one target big score in 2010. For me it totally depends what it is as I could easily keep something worth 10k if I liked it, but sell something worth a couple hundred if I had little interest in the history of the find. Bottles and modern jewelry would be two of the type of things that would hit the auction block if I found something decent.
