Ok. What do they go for?
Here is the auction I based my price on:
http://completed.shop.ebay.com/i.html?rt=nc&LH_Complete=1&_nkw=junk%20mercury%20dimes&_dmd=1&_dmpt=Coins_US_Individual&_fln=1&_sop=10&_trksid=p3286.c0.m283
Since it is the most recently closed auction, I figure it would be most up to date prices.
Then again, didn't I say "or best offer"? Maybethe best offer will be $1000? So be it.
