I've updated my Prime Number set showcase, including a digital album, now complete 1499-present after getting a 1531 Grosz and a 1553 Mansfield Thaler back from our hosts. Fun set I dreamt up years ago tucked away in the "Other" category of the Showcases.

A prime accomplishment! I wonder how many different prime denominations there are, things like, I dunno, 7 groschen or 13 pence or something? Did you ever research that? As a fellow recreational mathematician I think your set is Googol to the plex on the coolness factor (see what I did there?)! Kind regards, George
Congrats, such a cool set!
You're only complete for a couple of years though...what's on tap for 2027?

I haven't looked into denominations. I was aware of the 7 groschen and 13 pence, but I don't know of any 11 or 17 something coins.
We'll have to see what the mint churns out in 2027. Currently thinking a palladium eagle would be nice, or maybe the modern Peace dollar if they're still making them then.

Congratulations!
Cool
Now you should do a perfect square set. You can start with 2025.
It wouldn't be a very big set -- only 8 coins, 1444 to present (38^2 through 45^2). 12^3 (1728) could be thrown in as the only perfect cube that falls into the AD dated coinage timeframe.
