I stumbled across two 2x2s that I remember getting in 1970ish. Each has what is listed as a large date and small date 1970-s cent. Based on comparisons of LIBERTY, the 9s and crease/no crease in the 7s, they very much look like small dates to me. They were immediately tucked away in 1970. I'm no cent guy, but I'd guess 60-61+. Much value in these?
I also found a 1970-D Lincoln listed as a Floating Memorial roof error. I can kind of see it, but wouldn't be surprised if it's made up.
These were giveaway items way back. Buy a few bucks (literally) of something and you get these free, so they were viewed as worth little over face. Thanks for any insights.
