The Greysheet Catalog (GSID) of the 3-Cent Silver, Proof (1851–1873) series of 3-Cent Pieces in the U.S. Coins contains 3 distinct entries with CPG® values between $400.00 and $22,000.00.

Proof 3 cent silver coins were struck from 1854 through 1873 and cover most years of the series, which spanned from 1851 through 1873. All 3 cent silver coins, designed by Engraver James B. Longacre, are scarce and generally priced in the mid hundreds and up.

3 cent silver coins, also known as "trimes," were used for the purpose of purchasing postage, which was 3 cents per letter in the early 1850s. The denomination was also popular for other uses in commerce but was phased out in 1873 along with other denominations, including the 2 cent coin and half dime.

While there are three subtypes in the 3 cent silver series, only two are represented in proof format. These include the Variety II (1854-1858) and Variety III (1859-1873). Overall, the scarcest proof issue is the 1854, which is generally a five-figure coin. Proofs dated 1855-1858 and the 1873 are also scarce and usually command four-figure prices.
