If you have a U.S coin, M is probably the monogram of the designer. I can think of at least 2 such coins, the Morgan dollar designed by (drum roll, please) Morgan, and the standing liberty quarter designed by MacNeil.
U.S. mint marks are
P = Philadelphia, 1980-present and 1942-45 on nickels
S = San Francisco, up to 1955, occasionally thereafter till 1975, proof coins 1968-present
D = Dahlonega, GA 1838-1861
C = Charlotte 1838-1861
O = New Orleans, up to 1909
D = Denver 1906-present
CC = Carson City, up to 1893
W = West Point, commemorative coins only, 1993-present
No mint mark means it was minted in Philadelphia.
No mint mark indicates that the coin was minted in Philadelphia.
The letter D is the mint mark so it can't both have a mint mark and not have a mint mark.Please see the related question for more information.
It depends on the mint mark, if any, between the eagle's claw and the "1/2" in the denomination. Retail prices for moderately worn 1852 quarter eagles are: No mint mark - about $150 "O" mint mark - $170 "C" mint mark - $730 "D" mint mark - $940
This usually means it has a "P" mint mark which is often not printed. It stands for Philadelphia. Also your coin may be worn too much and the mint mark is not visible any more.
The M is not a mint mark but on every coin and is on the right side. The mint mark is to the left od the date slightly above.
Please check your coin again. No US quarters were minted in 1922.Also "M" is the designer's initial and not a mint mark. The mint mark position on Standing Liberty quarters is on the other pedestal:No mint mark = PhiladelphiaD = DenverS = San Francisco
By 1925, Liberty nickels hadn't been minted for 12 years, and M isn't a mint mark.
You're looking at the designer's monogram - an M for H. MacNeil.The mint mark position is on the left-hand pedestal, above and to the right of the date. See the Related Question for more details.
The M causes a lot of confusion. It's not a mint mark, it's the monogram of the coin's designer Hermon A MacNeil (and yes, he did spell his first name with an 'o') The mint mark position is roughly symmetric on the pedestal on the other side of Miss Liberty: No mint mark = Philadelphia D = Denver S = San Francisco
It is the mint mark signifying that the coin was produced at the Mexico City mint.
The mint mark, if present, is located on the coin's reverse, in the triangular area between the word ONE and the tips of the eagle's tail feathers. No m/m = Philadelphia D m/m = Denver S m/m = San Francisco
The U.S. does not have a "M" mintmark. Look at the coin again and post new question.
"M" is the monogram of the coin's designer Hermon MacNeil, not a mint mark. You need to know its date and whether it has a mint mark to determine its value. Either post a new question with that information or check out a site like the one linked below.
The mint mark is below the date.
