What is an 1843-O Seated Liberty Dime worth?
This is one of the dates collectors hunt for. A genuine 1843-O is valuable in any condition, even well worn. That's exactly why fakes and altered coins turn up so often.
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 1843-O Seated Liberty Dime rare?
- Yes. Only 150,000 were made, 27th lowest of the 116 regular issues in the series.
- Is the 1843-O Seated Liberty Dime silver?
- Yes. It's 90% silver, 10% copper and holds 0.0773 troy ounces of pure silver.
- Where is the mint mark on an 1843 Seated Liberty Dime?
- On the reverse, below the bow of the wreath or inside the wreath, depending on the year. Philadelphia dimes have no mint mark. On this coin the mark is O, for New Orleans.
- Which New Orleans dates near 1843 are scarcer?
- None. Within five years either side, no New Orleans issue had a smaller mintage than the 1843-O.
- How many 1843-O Seated Liberty Dime coins were made?
- 150,000.
What to check on your 1843-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 1843 (1.4 million made).
- 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.
- 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 is the key: a full, readable LIBERTY marks a coin in Fine or better. Then check Liberty's head and knee.
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 mint mark and date have not been tooled or added, or buy one already certified by PCGS or NGC.
The story of the 1843-O
Production at New Orleans fell off a cliff in 1843. Only 150,000 were made, against 2 million the year before. That drop is why the 1843-O is the one people look for. After that, New Orleans didn't make another until 1845.
The other mint made far more that year: 1843 alone came to 1.4 million, roughly 9.1 for every 1843-O. If you're checking a pile of 1843 coins, the O is the one to look for. In the whole series, its mintage sits closest to the 1863-S (157,500) and the 1860-S (140,000).
Only the 1860-O has a lower mintage among New Orleans's 19 Seated Liberty Dimes. Within the 1840s it's 3rd smallest of 17, between the 1844 (72,500) and the 1845-O (230,000).
New Orleans at full stride and the 1844 (1841 to 1845)
With the drapery design settled, both mints turned out dimes in volume. New Orleans passed two million in 1841 and again in 1842, striking 2,007,500 and 2,020,000, more than Philadelphia managed in either year. Philadelphia stayed between 1,370,000 and 1,887,500 from 1841 to 1843 and reached 1,755,000 in 1845. Proofs of these years were struck only in tiny numbers and are almost never seen. For ordinary dates of this stretch, a worn coin is a common sight and an easy addition to a set.
The scarce coins come from the dips. New Orleans made only 150,000 dimes in 1843 and none at all in 1844. Its 1845-O run of 230,000 is also elusive, especially with a full shield. The great rarity of the era is the Philadelphia 1844, with just 72,500 struck. Collectors have long called it Little Orphan Annie. Few were saved at the time and it is hard to find in any grade.
Dimes of 1841 to 1845 often turn up with heavy wear, scratches or old cleaning. Read the date carefully on an 1844, since a 4 can be faked on another year. Then judge the grade by the word LIBERTY on the shield: if every letter is clear, the coin is at least Fine. For the New Orleans issues, check that the O mint mark on the reverse is sharp and sits cleanly in the field.
How to recognize it
Liberty sits on a rock, her right hand resting on a shield crossed by a scroll reading LIBERTY. Her left hand holds a pole topped by a liberty cap and the date is below. The 1837 and 1838-O coins have nothing else on the obverse. From 1838 to 1860 thirteen stars surround her and from 1860 the words UNITED STATES OF AMERICA take their place. Drapery hangs from her left elbow on coins from late 1840 on. Arrows flank the date on most dimes of 1853 to 1855 and of 1873 to 1874. The reverse shows ONE DIME inside a laurel wreath ringed by UNITED STATES OF AMERICA until 1860. After that a larger cereal wreath of corn, wheat, maple and oak leaves surrounds the words. Branch mint marks are on the reverse near the bow.
