I know, the Lincoln Memorial Cent is not the smallest but if you look at the last photo, it is. That's the size of it. I blew the first two photos up just you could see it. It's copper but not only is it small, it's 3/16's of an inch actually.
The rims were completed. Show a photo next to a regular one for comparison. If it was a small planchet and struck, the rims would be missing or incomplete. Someone damaged this after minting. Most likely it sat in some acid and got smaller. Someone will know.
Yes, those are cool, but no, this piece is just one of those miniature novelty coins like I posted in the previous post. The molecularly altered pieces that Stoneridge Engineering does with electrical current are not shrunken down as small as the miniature novelty pieces, which are probably cast.
That gives all sorts of articles about inflation, not miniature coins. But I suppose maybe these sets of miniature novelty coins might have been sold under the joke title "Inflation Money" at some point.
Hm. Nope, not even with Google Image search. My results varied. But anyway, yeah. Those. Miniature novelty coins. Call 'em "Inflation Money" or not. I suppose some sellers have.
Been selling them since at least the mid 70's and I am fairly certain before that. You can find them at most coin shows. i cannot tell you how many thousands of the sets I have seen for sale over the years.
I also had (have?) one of these sets. I bought it at Stuckey's decades ago, probably for $1.00. I think they are plastic? I'm not sure if anyone will remember Stuckey's or not. They went away many years ago. But they sold novelty sets like this.
