Yeah, I'd say it's not likely we'll see a shortage of dateless buffs. Perhaps a hobo penny would be interesting, with zinc showing through the copper?
I was noticing that in 2005, they minted nearly 8 billion cents. 8 thousand million. That's pretty astounding.
In '36, they minted 118 million buffs, so find a nice low grade one and go for it. =)
And post pics!
Specks, can we see some of yours?
I'd be crushed to see a 1798 dollar hobo'd, but it's hard to imagine a world where there is a significant shortage of 1936
Buffalo nickels.
As for working on Jefferson's, I see that '38-'42's are the same composition as the buffs, so perhaps a '41 (200M+ minted) would make for a really cool art piece about WWII. You can get full rolls of them for under $10 on
ebay...
