Is Anyone Here A Collector Of Gold Florins?

There were a few others, but the systematic debasements of the existing ones made them useless for trade after centuries of use. What's remarkable is that the florin/ducat weight standard persisted while the solidii and dinars faded away in history. Maybe it was the tremendous production of Spanish gold escudos.

The other common name for the pistole is the doblon or doubloon, except in America where a doubloon was 8 escudos.

I won my Aragon dineros. Another story for another thread.

Very nice that you are writing about medieval Poland!

The easy question: the florin had a diameter around 20 mm, just a bit larger than a modern dime.

The other question ... If Casimir held a gold coin, it could have been a number of things.
A Bohemian florin like this one: https://en.numista.com/91048
Poland had close political ties to Bohemia (they had been ruled briefly by Bohemian monarchs of the Przemslyd dynasty at the turn of that century)...
... or a Hungarian one: https://en.numista.com/49299 Remember that Casimir was linked by marriage to the Hungarian royal family: his sister married king Charles Robert of Hungary in 1320, and Poland would be ruled by a Hungarian monarch (their son) after Casimir's death. So there would undoubtedly have been contact between the Polish and Hugarian courts by 1331, and the notion of florins being used for gifts, dowry, etc is possible.
... but most likely an Italian one as these would have been available in vastly larger quantity, and had become a common medium for international trade, or other large cash transfers (ransoms of kings or nobles, buying a small principality, etc.). The Bohemian and Hungarian versions were much newer, so fewer would have been in circulation by 1331.
Lastly, there is evidence that some small principalities in Italy were also striking imitation florins by around 1315. Apparently the two famous Polish hoards/treasures dating to the first half of the 14th century contain a mixture from various sources, including imitations.

It almost doesn't matter, because if you plan only to describe the coin ... THEY ARE ALL THE SAME! A lily on one side, and Saint John the Baptist on the other.

Probably the next most common gold coin in wide circulation at this point would have been the gold Genovino https://en.numista.com/417484 .
Genoa had a well established trade in the eastern Mediterranean and Black Seas. Casimir would eventually gain territorial access to the Black sea later in his reign (1349) at which point contact with Genoese gold coin woud have been more likely.

Yes, any gold coins would have seemed rare and valuable to 95% of people, but not to the upper class (just like today... how many Americans have ever possessed a one ounce gold coin like a double eagle, krugerrrand or maple leaf?).

An aside ... His predecessor, Wlasyslaw Lokietek, had struck the first Polish gold coins, but based on their exceeeding rarity, probably relatively few were ever sruck. https://en.numista.com/138147https://en.numista.com/138147
This type was NOT mentioned in the accounting of the gold coins in the Polis hoards.

I am originally from Philly, where my grandfather arrived from Poland in 1907. In Ohio since 2011.

Yes on the denari and prager groschens. The silver denars were tiny coins, about half the diameter of a U.S. Lincoln Cent, and only 1/10 the weight. These photos are lacking scale (something for comparison) but give an example of what they looked like (Casimir''s portrait on one side, and the Piast eagle on the other)



Possibly the design was copied from a Hungarian denar like this:

...taking into account that the fleur-de-lis device on the Hungarian coin represented the House of Anjou, but the eagle on the Polisch coin stood for the Piasts. Again, maybe evidence of the Polish-Hungay connection of that era.

I will try to get a photo of some of these coins with a U.S. coin for comparison and post later.
