A striking copper - minted trojak piece 1818.
This is a very rare, 19th century minting for collectors' use made at the Warsaw Mint (the so-called "new minting" or "novation").
Beautiful state of preservation. Uncirculated detail. Even patina. Prominent mint luster.
Beauty appreciated with the highest NGC note.
The edge is obliquely fluted.
Numismatic very rarely seen in the trade
