About this coinHistory

First proof of the denomination and one of the earliest proof minor coins from the Philadelphia Mint, the 1851 proof three-cent silver had a minuscule production. Estimates suggest fewer than two dozen were struck, making the 1851 proof one of the rarest trimes in any format. The coins were produced for presentation purposes and for the tiny community of collectors active in the early 1850s.

Surviving examples appear at auction very rarely. When one does surface, it commands strong prices reflecting both the extreme rarity and the historical significance of the first-year proof. The 75% silver composition of Type I gives the proof a slightly different surface character than the later 90% silver proofs, with a subtly cooler tone that specialists can sometimes detect by eye.
