These were all in the same box I searched recently. Besides the usual 10 or so wheats, which yielded little except a nice 1927 P. They are all 1963 P.
Should have seen the 74 or so 1943 Steelies in XF-AU I found in a box about three years ago. Someone must have dumped a collection into a coin machine, kind of surprised steel made it through and didn't get rejected. But I have occasionally even found plastic play money cents in BWR.
Yeah, there's a lot out there. Id suspect it's people carelessly dumping collections. But sometimes I get rid of proof coins, so u never know.
