I Hit The JFK Proof Jackpot

I am sitting on a lot of circulated proofs that I found crh one day when I retire crh I will through them back into circulation

Nice finds! I found once maybe a dozen or so S-mint Kennedy proofs for a $500 box (it was at a Bank of America). That said, they aren't worth as much as you think mostly due to them not being silver. I sold some of my duplicate impaired/slider proofs for around $1.15 per coin on ebay a few years ago, so while they aren't worth too much, I still look for dates as anything 1971+ for halves are Proof only for me unless if a rare variety.
