Peter III 10 Kopecks 1762, Diakov-32 (R1), AU53 Brown NGC. Obv. Crowned double-headed Imperial eagle. Rev. Date and value. Overstruck on an Elizabeth 10 Kopecks, with a considerable amount of the undertype visible. The strike is rather crude due to having been struck over the earlier coin. Taking all things into consideration, this piece is exceptional for the type, which normally comes in lower grades with poor details. Rare in this condition.
