Assuming you have an American coin, you have to first know where its mint mark position is. On older coins it's often on the back side of the coin near the bottom of the design, but not always. If you go to a site such as www.CoinFacts.com they have pages about almost every coin ever minted in the U.S.; each one tells you where the mint mark position is.
Next you have to know what mints were operating at the time and what letter if any they used. For example, most coins minted at Philadelphia before 1980 don't have any mint mark so looking for a "P" is fruitless. Similarly, a "D" mint mark might mean Dahlonega, Georgia or Denver, Colorado depending on when a coin bearing that letter was minted.
Here's a list of the mint mark letters used on American coins:
S = San Francisco (1854-)
D = Denver (1906-)
D = Dahlonega (1831-61)
C = Charlotte (1831-61)
O = New Orleans (1838-1909)
P = Philadelphia (on nickels 1942-45, dollars from 1979 on, all others except the cent 1980 on)
CC = Carson City (1870-93)
W = West Point (1984-, on non-circulating collector coins only)
Those letters are mintmarks that tell where the coin was minted. S means it was minted in the San Francisco Mint.
