About this coinHistory

The 1977-S Proof cent was produced at San Francisco with a mintage of approximately 3.25 million pieces, included in that year's proof sets. The proof program continued smoothly under San Francisco's watch, with consistent quality and steady collector demand.

The 1977-S Proof cent shows well-struck devices on deep mirror fields. By this point in the proof series, the Mint had refined its techniques, and cameo contrast was becoming increasingly common on early-strike proofs. The coin is affordable and widely held. Collectors add it to their proof sets as a matter of course.
