A hard-to-get technological sample of the first twenty-dollar coin with Marceli Nowotko.
Minted in cupro-nickel in an edition of only 20 pieces.
Mint, with patina on the surface and mirror.
Made with a different obverse stamp than the nickel issue (smaller eagle), as shown in Janusz Parchimowicz's "Polish Sample Coins 1949-1990" catalog.
