What is an 1870 Seated Liberty Quarter worth?
Few coins in the series are harder to find. Even a worn 1870 sells well above face value. The flip side is that counterfeits and altered dates are common, so authentication matters.
What would make yours worth more:
- Uncirculated condition with full original luster
- A die variety or minting error
- Certification by PCGS or NGC, which buyers expect for scarce dates
For market prices, check recent sold results for certified coins in the same grade.

What to check on your 1870
- There's no mint mark on this one, so the date and condition are what matter.
- Check the date and mint mark under magnification for tooling or added letters. Scarce dates are the ones forgers alter.
- Don't clean it. Cleaning leaves fine scratches and an unnatural shine that collectors avoid.
- Proof or circulation strike? A proof has mirror-like fields and frosted design details and was sold to collectors, not released in change. The 1870 Seated Liberty Quarter Proof (1,000 made) is the one to compare with.
- Old coins pick up damage over a long life. Look for holes, bends, scratches or signs of cleaning before you judge the grade, because a damaged coin sells for a fraction of a problem-free one.
- Judge the grade under good light. The word LIBERTY on Liberty's shield is the classic test: fully visible in Fine, partly worn in Very Good, gone in Good.
Never clean it. Collectors pay strong premiums for original surfaces and natural toning on a date like this. A cleaned coin can lose half its value or more. Low-mintage dates attract altered and counterfeit coins. Check that the date have not been tooled or added, or buy one already certified by PCGS or NGC.
The story of the 1870
Philadelphia ramped up hard in 1870: 86,400 coins, about 5.4 times the 1869 run. The next year it made 118,200 (1871).
It was the big producer of the year, well ahead of 1870-CC (8,340). In the whole series, its mintage sits closest to the 1842 (88,000) and the 1851-O (88,000).
Philadelphia struck the Seated Liberty Quarter in 56 issues between 1838 and 1891. By mintage this one lands in the scarcer half, while the key for that mint is the 1886 (5,000). Within the 1870s it's 9th smallest of 28, between the 1872-S (83,000) and the 1871 (118,200).
IN GOD WE TRUST joins the reverse (1866 to 1872)
In 1866 the motto IN GOD WE TRUST was added on a ribbon above the eagle. Silver still did not circulate in the East, so Philadelphia struck only 16,800 business strikes that year and similar small numbers through 1869. San Francisco carried more of the load, but even its mintages stayed below 100,000 in every year of the period.
The Carson City Mint in Nevada struck its first quarters in 1870. The 1870-CC (8,340 struck) and the 1871-CC (10,890) are among the toughest dates in the whole Seated series. The 1872-CC, with 22,850 made, is scarce as well. Survivors from this period are often well worn, cleaned or damaged because many circulated for years in the mining West. Philadelphia proofs of 600 to 1,000 a year are the usual way collectors fill these dates in high grade.
Elsewhere in US coinage in 1870
The Carson City Mint in Nevada began striking coins in 1870, using silver from the Comstock Lode. Its "CC" mint mark is now among the most sought after.
How to recognize it
Liberty sits on a rock holding a shield inscribed LIBERTY and a pole topped with a liberty cap, with 13 stars around her and the date below. The reverse shows an eagle with QUAR. DOL. below. Arrows beside the date (1853 to 1855 and 1873 to 1874) and rays around the eagle (1853) mark weight changes. The motto IN GOD WE TRUST appears above the eagle from 1866.
