1870

The 1870 three-dollar gold piece was the first issue of the series struck after the death of James B. Longacre, who had passed away on New Year's Day 1869 after almost two decades as Chief Engraver. William Barber inherited the post and the working dies, and the Indian Princess obverse paired with the Type 2 reverse continued without alteration. Philadelphia produced just 3,535 circulation strikes, a figure that places the date squarely in the scarcer middle band of the series. The same year carries an outsized historical footnote in numismatic circles, since the unique 1870-S Proof was struck in San Francisco and now resides in the Bass Foundation collection, catalogued separately on this site. PCGS estimates roughly 60 to 90 survivors across all grades for the Philadelphia date, with most pieces clustering in the Very Fine to About Uncirculated range.

Authentication at this Semi-Key tier demands close inspection because the date invites both period transfer-die work and modern cast forgeries. A genuine 1870 weighs 5.015 grams within a narrow tolerance and measures 20.5 millimeters across a clean reeded edge that should show no seam, file ghost, or solder shadow from a former jewelry mount. The reverse must display the Type 2 layout, with the larger DOLLARS legend and open wreath at top, and the obverse headdress feathers should retain their fine internal striations rather than blending into a soft mass. Cast counterfeits betray themselves through grainy fields, mushy headdress detail, rounded denticles, and date numerals that read puffy rather than sharply serifed. Any magnetic pull or a weight outside roughly 4.95 to 5.08 grams ends the discussion before laboratory testing becomes necessary.

For collectors today, the 1870 fits naturally into any Reconstruction-era gold cabinet and offers a tangible link to the brief Barber transition at the Mint. Original honey-gold surfaces are uncommon, and cleaned or lightly polished examples outnumber unmolested coins by a wide margin in the marketplace. Certification by PCGS or NGC is effectively required at this price tier, and a CAC sticker carries additional weight in the higher circulated grades where eye appeal drives bidding.
