1859 Liberty Seated Silver Dollar. Proof-63+ Cameo (PCGS).Virtually untoned surfaces are fully struck with a bold cameo finish from the dies. Lovely Choice quality from a Proof mintage of 800 pieces, survivors of which are scarce to rare in all grades due to the fact that many unsold examples were later released into circulation. In fact, it is likely that no more than 450 specimens were actually distributed to contemporary collectors, mostly as part of the years silver Proof sets.
