AV Goldgulden ND 22mm./ 3.54g. Kremnitz Mint struck 1455-57 Ladislaus V King of Hungary 1453-57 Antykwariat Numizmatkyzny Auction/ Warsaw/Poland
How boring! Just another everyday Panzerman gold coin worth ten times more than anything in my entire collection. Don't you have anything interesting, like a DDO 17th century ducat with a rotation error?
That is quite coincidental as I was just looking at this modern coin as a possible purchase. https://www.coinsweekly.com/en/News/Hungarian-Mint-issues-the-gold-florin-of-Sigismund/4?&id=4404
They made some really nice AV 10 Goldgulden coins dated 1499 under Wladislaus II/ even a 20 Goldgulden! Probably the 20 Goldgulden was the heaviest gold coin since the Bactrian AV 20 Stater which was in Emperor Louis Napoleon III's collection.
