What is an 1859-O Seated Liberty Half Dime worth?
Collectors pay a real premium for this date, worn or not, because far fewer were made than usual. Uncirculated pieces go much higher.
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.
Quick answers
- Is the 1859-O Seated Liberty Half Dime rare?
- Somewhat. 560,000 were made, fewer than most dates, so collectors treat it as a semi-key.
- Is the 1859-O Seated Liberty Half Dime silver?
- Yes. It's 90% silver, 10% copper and holds 0.0359 troy ounces of pure silver.
- Where is the mint mark on an 1859 Seated Liberty Half Dime?
- On the reverse, below the bow of the wreath or inside the wreath, depending on the year. Philadelphia coins have no mint mark. On this coin the mark is O, for New Orleans.
- Which New Orleans dates near 1859 are scarcer?
- None. Within five years either side, no New Orleans issue had a smaller mintage than the 1859-O.
- How many 1859-O Seated Liberty Half Dime coins were made?
- 560,000.
What to check on your 1859-O
- Make sure the mint mark really is a O. A worn or filled mark can be misread. It's what separates your coin from the 1859 (340,000 made).
- 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 1859 Seated Liberty Half Dime Proof (800 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. LIBERTY on the shield wears first; a full LIBERTY marks Fine or better. These tiny coins are often bent, cleaned or holed.
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.
The story of the 1859-O
New Orleans made 560,000 in 1859, down from 1.7 million in 1858. The next year it made 1.1 million (1860-O).
1859 came to 340,000, so neither mint's 1859 coin is much scarcer than the other. In the whole series, its mintage sits closest to the 1870 (535,000) and the 1848-O (600,000).
New Orleans struck the Seated Liberty Half Dime in 21 issues between 1838 and 1860. By mintage this one lands in the scarcer half, while the key for that mint is the 1838-O (70,000). Within the 1850s it's 5th smallest of 22, between the 1859 (340,000) and the 1855-O (600,000).
Arrows removed and big Philadelphia runs (1856 to 1859)
The arrows came off in 1856, though the 1.24 gram weight stayed. Philadelphia struck 4,880,000 half dimes that year and 7,280,000 in 1857, while New Orleans made 1,100,000 and 1,380,000. Spanish and Mexican silver lost its legal tender status in 1857, which raised demand for American small change. New Orleans struck more than a million half dimes in each of 1856, 1857 and 1858. That same law replaced the large copper cent with the small Flying Eagle cent.
Philadelphia's 1858 total of 3,500,000 includes a well known error, the date over inverted date. The date was first punched upside down and then corrected. Traces of the inverted digits can be seen around the date. New Orleans struck 1,660,000 in 1858. Output then dropped in 1859, to 340,000 at Philadelphia and 560,000 at New Orleans. Philadelphia's 7,280,000 coins of 1857 are the second largest half dime mintage, behind only the arrows coins of 1853.
Proofs were made in quantity from 1859, when 800 were struck. For collectors these years are an easy way to add Seated half dimes with the stars obverse, since most dates are common. Check the 1858 date with a strong glass for the inverted traces. On any coin of the period, look for the O mint mark on the reverse and judge the wear on Liberty's knee and the shield.
Elsewhere in US coinage in 1859
The Indian Head cent replaced the Flying Eagle cent in 1859. Its first-year reverse showed a laurel wreath, replaced by an oak wreath and shield the next year.
How to recognize it
Liberty sits on a rock with her right hand on a shield crossed by a scroll reading LIBERTY and her left hand holding a pole topped by a liberty cap. The 1837 and 1838-O half dimes show nothing else on the obverse but the date. From 1838 to 1859 thirteen stars ring the design and from 1860 they are replaced by UNITED STATES OF AMERICA. Drapery falls from her left elbow on coins from late 1840 on. Arrows beside the date mark the lighter coins of 1853 to 1855. Until 1859 the reverse shows HALF DIME inside a laurel wreath circled by UNITED STATES OF AMERICA. From 1860 a cereal wreath of corn, wheat, maple and oak leaves surrounds HALF DIME alone. Mint marks for New Orleans and San Francisco are on the reverse near the bow.
