Where is the mint mark? U.S. coins by type
Mint-mark locations for U.S. cents through dollars: Lincoln under the date, Buffalo under FIVE CENTS, Mercury right of ONE, Peace at the eagle’s wing tip, Morgan under the eagle, and more.
A mint mark is a small letter that tells you which U.S. Mint struck the coin. Many coins have no mint mark because for a long time Philadelphia was the only mint — and Philadelphia often left coins unmarked.
This page is a location field guide for common U.S. types people pull from jars and estates. Diagrams use real coin photos where possible. Always confirm on the piece in hand with good light and a loupe. Finding a letter does not make a coin rare — see old is not rare.

Mint letters (what they mean)
- No mark — usually Philadelphia (1793–date on many series)
- P — Philadelphia (wartime nickels; many modern non-copper issues from 1982 on)
- D — Denver (1906–present on circulating coinage). Note: early gold also used D for Dahlonega, Georgia (1838–1861 gold only)
- S — San Francisco (1854–date)
- O — New Orleans (1838–1909 era issues)
- CC — Carson City (1870–1893)
- C — Charlotte (early gold only, 1838–1861)
- W — West Point (mostly special / collector issues)

How to use this without inventing a letter
- Identify the coin type first (Morgan vs Peace, Buffalo vs Jefferson, etc.)
- Write date + mint on paper before searching online
- If you cannot read the mark, do not invent a D or S from dirt
- Keys still need condition — use pull lists for wheats, Buffalos, Morgans
