1855 Proof

The 1855 Seated Liberty Dollar Proof is struck at the Philadelphia Mint with an estimated 30-piece original mintage. The 1855 Proof carries the standard Christian Gobrecht obverse and the No Motto reverse that defines the early series through 1865; the live page mintage of 26,000 reflects the circulation-strike figure rather than the proof mintage. The 1855 Proof continues the mid-1850s proof production at modest volumes, with collector demand for proof Seated Dollars limited during the period when the silver-dollar denomination saw restricted circulation use.

Authentication of an 1855 Seated Dollar Proof requires careful examination of strike quality, mirrored field character, and surface preservation under five to ten power magnification alongside documented pedigree. The 1855 Proof shows fully struck Liberty drapery, sharp eagle feather definition, and deep mirror fields that distinguish formal proof production from business-strike prooflike examples. PCGS, the Professional Coin Grading Service, and NGC apply standard proof grading conventions across the Seated Dollar proof sequence. Cameo and Deep Cameo designations are uncommon for 1855 Proof examples.

The 1855 Seated Dollar Proof is a regular-classification proof entry on this site under the standard catalog convention for Seated Dollar proofs, with the trophy-tier rarity reflected in the prose rather than the badge tier. The 1855 Proof pairs with the 1854, 1856, and 1857 P-mint proofs as the matched mid-1850s proof sequence. Auction records for confirmed 1855 Proof examples reach into the five figures for mid-grade and six figures for high-grade Cameo examples. Specialist Seated Dollar proof collectors typically target the complete 1840-1873 P-mint proof run by year, with the No Motto / With Motto type-transition pair and the restrike issues forming key sub-collecting milestones within the broader proof set assembly project. Pedigree documentation for known examples threads through major collection sales including those held at Stack Bowers, Heritage Auctions, and earlier Bowers and Merena catalogs that continue to anchor the modern certified-population research.
