How much do these sell for in the second hand market? I had a look around but price information seems to be limited. I would like to get some of these if I can stack them cheap enough.
eBay says $600+ On forums it's selling at around $350. Can't say how much it's worth, it's pretty much worth whatever people are willing to pay for.
Would hazard a guess of $50 max per coin. It's very hard to sell random proof coins by itself when its broken away from it's set.
If 3 of a 5 coin year set is sold together then that would be more desirable as a stacker may already have a few of the random coins for that set already?
