Costa Rica, stainless steel 10 centimos, 1958 BCCR, NGC Mint Error UNC details, double struck with obverse indent / reverse wheel mark. KM-185.1a. Very brightly lustrous, with ghosting of letters due to the faint doubling and egregious void on the date with associated protrusion of the metal past the usual edge, machine-made diagonal haziness on reverse. Pedigreed to the Tamarindo Collection of Costa Rican Error Coins and Paper Money.
