1877

Few dates in the Coronet Head series carry the structural weight of this Philadelphia issue. With Mint Director Henry Linderman pressing for a cleaner, more legible coinage, Chief Engraver William Barber re-cut the reverse hub, replacing the abbreviated "TWENTY D." that had served the denomination since 1866 with a fully spelled "TWENTY DOLLARS." Barber also tightened Liberty's portrait, repositioning the coronet so its peak nestles between stars six and seven, and adjusted the neck truncation. These modifications opened the Type 3 chapter that would run uninterrupted for thirty-one years, making 1877 the bookend every type collector chases when assembling a three-piece Liberty Head Double Eagle set.

Production at Philadelphia totaled 397,670 business strikes, a respectable figure for the era yet one that masks how thinly the date is represented in higher grades. PCGS CoinFacts characterizes the issue as comparable in rarity to the 1854, 1860, and 1878, and notes that average uncirculated examples are very scarce while choice Mint State coins are rare. Most survivors fall in the EF to AU window, often with the bagmarks and rim ticks expected of a coin that circulated freely in commercial channels. Strike quality on early Type 3 Philly pieces tends to be sharper than the late Type 2 dates, a direct dividend of Barber's recut hubs and refreshed dies. A separate twenty-piece proof printing exists but trades as a wholly different animal from the business strike.

Auction evidence reinforces the population picture. Stack's Bowers sold a PCGS MS-60 example for $1,380, a figure that anchors the entry-level Mint State market and underscores how steeply premiums climb above that grade. Set against the 1876 (the final Type 2 year and a date with a Philadelphia mintage roughly an order of magnitude larger) and the 1878 (the second Type 3 year, more available across the grading spectrum), the 1877 occupies a transitional pocket: historically pivotal, structurally scarce in mint state, and the only date that can simultaneously close a Type 2 set and open a Type 3 set in the broader Liberty Head Double Eagle series history.
