Seated Liberty Dimes
1859 10C PF
Description & Analysis
Though no official records were kept of proof coin sales before 1860, it was later reported by a Mint official that 800 complete silver proof sets were struck for 1859. This figure proved to be highly optimistic, and it's likely that more than half of the 1859 proof dimes were melted after the end of the year.
Another milestone was achieved with 1859's proof dime production in that two die pairs were used instead of the usual single pair. No currency pieces were struck from any of these dies.
