In short:<\/strong>
\nMint marks on US coins indicate the mint where a coin was struck. This article explains the most important marks, such as P, D, S, W, O, CC, and C, their historical development, and why mint marks can be important for identification, rarity, and collector value. <\/strong><\/p>\n

Mint marks are letters on a coin that indicate the mint’s origin. Originally, they served to identify the respective mint for its weight, fineness, and finish. When the United States still minted circulation coins from precious metals such as gold and silver, a commission regularly reviewed the composition and quality of coins from all locations. This ensured that each mint worked precisely according to specifications. <\/p>\n

What exactly is a Mint Mark<\/strong><\/h2>\n

A mint mark<\/a> is a one- or two-letter code on the coin. It represents the mint and helps distinguish between years, varieties, and production methods. For collectors, it is therefore an important piece of data for identification, valuation, and provenance. <\/p>\n

The early years \u2013 Philadelphia without license plates<\/strong><\/h2>\n

In the early years, Philadelphia was the only minting location. Since there were no other locations, a mint mark was unnecessary. It wasn’t until 1838 that the U.S. Mint opened additional branches: Charlotte, Dahlonega, and New Orleans. Mint marks first appeared on U.S. coins at these locations. Philadelphia itself remained unmarked. <\/p>\n

1942 \u2013 the \u201cP\u201d appears on the war nickels<\/strong><\/h2>\n

In the midst of World War II, nickel was removed from five-cent coins. In 1942, the “P” first appeared on nickels minted in Philadelphia. At the same time, the symbol moved from the right side of Monticello to the top of the dome to indicate the changed alloy. After the war, with a return to the standard alloy, the symbols returned to their previous positions, and Philadelphia initially stopped using the “P.” <\/p>\n

1965 to 1967 \u2013 no mint marks<\/strong><\/h2>\n

The Coinage Act of 1965 temporarily abolished mint marks. The goal was to curb hoarding and collecting while the Mint met the demand for circulation coins. Therefore, between 1965 and 1967, circulation coins bore no marks. <\/p>\n

From 1968 \u2013 license plate on the front<\/strong><\/h2>\n

With the return of the hallmarks in 1968, their placement changed to the obverse of the coins. Before that, they were usually on the reverse. <\/p>\n

1979 to 1980 \u2013 the \u201cP\u201d returns<\/strong><\/h2>\n

With the introduction of the Susan B. Anthony dollar in 1979, the “P” reappeared. Starting in 1980, every denomination except the cent bore the “P” provided it was minted in Philadelphia. This placement remains in place today.<\/p>\n
