Actually those mint marks are on new coins, too.
D means the coin was minted in Denver.
S means it was minted in San Francisco.
Most coins minted at San Francisco since 1968 are special collectors' coins called proofs. However there were some nickels and pennies minted for circulation during the late 1960s and early 1970s, as well as some Susan B. Anthony dollars; these turn up in change very occasionally.
The D is a mint mark, indicating that the coin was struck in Denver. Other mint marks on modern coins are S = San Francisco, on circulating coins up to 1955 and occasionally from 1968 to 1975, and on proof coins from 1968 onward. P = Philadelphia, on coins from 1979/80 onward, and 1942-45 nickels. Coins without a mint mark are also from Philadelphia. W = West Point, on commemorative coins only.
Simple answer is: 1909-S / 1909-S V.D.B. / 1914-D / 1922 no D / 1931-S and the 1943 Bronze and 1955 Doubled-Die error coins.
Minted Denver, CO.MoreA "D" on any coin minted since 1906 means it was minted in Denver, Colorado. Other mint marks you may see are:"P": Philadelphia (but current Philadelphia pennies, and Philadelphia coins before 1980 except wartime nickels, don't have mint marks, so it gets confusing)"S": San Francisco (on older coins and modern proof sets)Coins minted over 100 years ago may also have an "O" for New Orleans, "CC" for Carson City, and very old gold coins may have a D or C on them but you won't find any of them in change!
There was a brief period of 1965-67 when no U.S. coins had any mint marks. However, since 1968, D and S mint marks returned, and P was added to most coins in 1980. Philadelphia pennies still lack a mint mark, but Denver ones are marked with D, and proofs from San Francisco have the S.
The "S" and the "D" are called mint marks which identify which US Mint produced the coin. Coins with no mint mark prior to 1980 were minted at Philadelphia. Just having an "S" or a "D" mint mark does not mean the coin is worth more. The value of a coin is generally determined by the demand collectors and investors have for the coin. The more people who want to own it, the more it is worth.
The U.S. does not have any "F" mintmarks. Only P-D-S & W for any coins.

If you mean a "Mintmark"? They are small letters ( O, S, CC & D) on the reverse of the coins.
D = Denver S = San Francisco also P = Philadelphia assuming question means USA coins
The letters under the dates on Lincoln cents are mint marks and can only be a D or S and are used to identify which mint made the coin. D is for Denver, S is for San Francisco. Also coins with no mint mark means it was made in Philadelphia.

No D's in 1928. The coins were only struck in Philadelphia and San Francisco. The S coins run from $30.00 to $70.00 in circulated grades.
If you are talking about U. S. coins, it means that coin was minted in San Francisco. Coins for circulation today are minted in either Philadelphia or Denver. Those from Denver have a "D." Philadelphia coins in some denomination from some time periods have a "P" but those without a mint mark also come from Philadelphia.

??? Pennies are 1-cent coins, nickels are 5-cent coins. Saying "penny nickel" is like an "inch foot" and doesn't mean anything. Please post a new question after you determine what you have, including its denomination and mint mark (on a cent, there might be a D or S under the date, on a nickel there will be a P, D, or S above the dome of Monticello on the back)
