1887 Proof

The 1887 proof half dollar carries the lowest proof delivery in the unbroken 1879 through 1890 Philadelphia run and the smallest figure for the denomination since 1877. Mint records put the issue at 710 pieces against just 5,000 business strikes for the same calendar year, so proofs accounted for roughly twelve percent of total 1887 half dollar production. That ratio inverts every pre-1879 norm, when business strikes ran into the millions and proofs hovered in the few-hundred range. The structural cause was the Bland-Allison Act of February 1878, which obligated the Treasury to coin two to four million dollars of silver into Morgan dollars each month and drained the allocation that would otherwise have flowed into fractional coinage. The 710 figure is a notable step down from the 886 proofs struck for 1886 and may reflect contracting subscriber rolls or specific weakness in the half dollar tier of the annual silver set.

Authentication rests on close-collar proof diagnostics rather than mirror depth alone, because the 1887 business strike is widely known for prooflike surfaces and the two issues are routinely confused. A genuine proof shows squared, perpendicular rims with a fine wire-rim ridge from the medal-press blows, watery deep-mirror fields with controlled die-polish lines visible under a 10x loupe (a jeweler's magnifier), and frosted devices with cameo contrast on early die states. Denticles, the tooth-like beads ringing the rim, should rise sharp and fully formed on both sides. A business strike, by contrast, shows rims that round into the field with no wire ridge and radial flow lines under magnification even when fields read as mirrored to the naked eye. Specifications must hold at 12.50 grams on a .900 fine silver planchet at 30.6 millimeters with a reeded edge. PCGS (Professional Coin Grading Service) or NGC (Numismatic Guaranty Company) certification is the working standard.

For collectors, the 1887 proof carries standalone scarcity inside the 1879 through 1890 cluster because of its position as the low-mintage anchor of that stretch, and pricing typically runs above surrounding dates rather than tracking the cluster average. Cameo and Deep Cameo (the frosted-device, mirrored-field contrast) designations carry meaningful premiums, and gem PR65 and finer pieces are scarce relative to the PR62 to PR64 band where most survivors cluster. The Regular classification follows site convention for proof entries; the date's place as the smallest delivery in the late-series run is conveyed in the prose, not the badge.
