I picked up a bag of halves today. I wasn't finding anything til the bottom of the bag. A few silvers and then a 1850 braided hair large cent. WOW. I was hoping to find one in the ground but I'll take it.
Go back and see if other bag denom are or will be available. Just never know if it was an all inclusive collection dump, of type coins maybe. Ask if you can have the contents of the internal JUNK BIN, might be some other interesting stuff in there.
