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 on completing your set.
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.

Very nice set. Can't wait to see the Early Dated coins
you add to your collection.
Neither can I

@messydesk Once you go backwards from A.D. 1465 it will be slim
pickens on finding coins. Most will be Islamic or Far Eastern coins.
