Watch List notes:

Costa Rica, nickel 20 colones, 1975, 25th anniversary of the Central Bank, struck 75% off-center, NGC Mint Error MS 65. KM-205. Just about as much off-center as you can get while still showing a full date, lustrous and choice, great for showing what a blank flan looks like. NGC #1527016-012. Pedigreed to the Tamarindo Collection of Costa Rican Error Coins.
