Literature: Szatalin BD20-2 R5, Kopicki 1270 R6
Very nice details and quality of minting, even gray patina. A very attractive piece.
A first, highly sought-after vintage, struck in a scarce mintage with the letters II-VE above the date numerals.
According to Gumowski, this was a proof issue, struck in 1620 in a small mintage.
A coin for the finest collections.
