About this coinHistory

Proof production continued in 1830 with another small run of specially prepared coins. The 1830 proof half dime is collected within the small population of early Capped Bust proofs, which number perhaps a few dozen total across all dates of the series. Each year's proofs were struck individually rather than as part of an organized proof coin program, making the surviving pieces scattered and irregularly documented.

The 1830 proof shows the Capped Bust design in sharp, fully struck detail. Collectors who pursue early proof American silver find the Capped Bust half dime proofs among the most affordable of the pre-1836 proofs, though "affordable" is relative when the surviving population may total fewer than 50 examples across the entire series.
