About this coinHistory

The 1991-S Proof was produced at San Francisco with a mintage of approximately 2.87 million pieces, one of the lower proof totals from this era. The slight dip in proof set sales may reflect the economic recession that affected consumer spending in 1991.

The proof cent features the expected deep mirror fields and frosted devices. Deep cameo contrast is common for this period. The lower mintage compared to adjacent years has not translated into a significant premium.
