- Where is the mint mark on an 1858 Seated Liberty Half Dollar?

- 7,294,000.
What to check on your 1858-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 1858-S (476,000 made).
- 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 benchmark for Fine. Check the high points of Liberty's knees and breast.
Circulated examples are usually traded for their silver content. Pick out the best ones: original luster and attractive toning lift a coin above melt, while cleaned coins lose most of their collector value.
The story of the 1858-O
New Orleans ramped up hard in 1858: 7,294,000 coins, about 8.9 times the 1857 run. The next year it made 2.8 million (1859-O).
1858-S came to 476,000 and 1858 came to 4.2 million, so neither mint's 1858 coin is much scarcer than the other.
Of the 24 Seated Liberty Half Dollars New Orleans struck between 1840 and 1861, none was made in bigger numbers. The scarcest New Orleans issue is the 1853-O, No Arrows at 4. No Seated Liberty Half Dollar of the 1850s had a bigger run.
Peak branch output and the 1861-O (1856 to 1865)
With the arrows gone, halves were struck in large numbers. New Orleans reached 7,294,000 in 1858. San Francisco's early halves, such as the 1856-S and 1857-S, are scarce in better grades. In 1861 New Orleans struck 2,532,633 halves under three authorities: the United States, the State of Louisiana and the Confederacy. Specialists use die markers to tell which authority struck a given coin. Four halves were also made with a Confederate reverse design.
During the Civil War silver disappeared from eastern circulation. Philadelphia mintages fell to between about 250,000 and 512,000 a year from 1862 to 1865. San Francisco, where coins still passed at face, struck more halves than Philadelphia in most of those years. Worn wartime Philadelphia halves are harder to find than their mintages suggest because many were melted later.
Elsewhere in US coinage in 1858
The Flying Eagle cent was struck for the last time, in Large Letters and Small Letters varieties, before the Indian Head cent replaced it.
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 HALF DOL. below. Arrows beside the date (1853 to 1855 and 1873 to 1874) and rays around the eagle (1853) mark weight changes and IN GOD WE TRUST appears above the eagle from 1866.
