1858-S

The 1858-S is the fifth-year San Francisco eagle and one of the toughest dates in the early Pacific $10 run that survives in collectible quantity. Coinage collapsed to just 11,800 pieces, a steep contraction from the 26,000 figure of 1857-S, struck the year after the Panic and during a stretch when San Francisco gold was being absorbed into Pacific commerce rather than banked as long-term reserve. That working-economy fate explains why the entire delivery was put through hard service and why almost nothing remains from the higher end of the production run. Doug Winter places survival at roughly fifty pieces across all grades, with the great majority showing heavy circulation and the date essentially unknown in Mint State on either certification census.

Of the survivors, perhaps fifteen reach the About Uncirculated tier, and Winter notes that nearly all have been dipped or are heavily abraded, recommending that buyers consider a problem-free EF45 or AU50 over a worn AU55 with surface issues. Authentication should confirm the statutory 16.718-gram weight and specific gravity near 17.2, with close attention to the S mintmark seated below the eagle's tail; added mintmarks transferred from common Philadelphia 1858 eagles remain the standard deception at this date level. Strike on genuine pieces tends to be acceptable but eye appeal is rarely the draw, what carries this coin is original skin, honest wear, and the absence of the dipping and rim damage that has been inflicted on most known examples over the past century.

The collecting landscape rewards patience over budget. Problem-free EF coins trade in the mid-to-high four figures, choice AU pieces move decisively into the mid-five-figure range, and any example approaching mint state, none currently certified, would set a date record on first appearance. For the No Motto type collector building the San Francisco subset, the 1858-S sits alongside the 1855-S and 1859-S as the trio of genuine condition rarities that define difficulty in this branch run, well above the more available 1854-S, 1856-S, and 1857-S.
