About this coinHistory

The 1978-S Proof cent was struck at San Francisco in a quantity of approximately 3.13 million pieces. The proof set program continued to attract a loyal base of annual subscribers. The coin features the characteristic mirror fields and frosted devices of San Francisco proof production.

President Carter's Camp David negotiations between Egypt and Israel represented a major diplomatic achievement in 1978. The proof cent, sealed in its set, bore no mark of these events. It remains affordable and widely available. Collectors of proof Lincoln cents include it routinely.
