There are been several different 4c stamps issued with Abraham Lincoln's face on it, so you will need to find out exactly which kind of stamp you have in order to determine what its value might be.
The most common Lincoln stamp is red violet in color with perforations around the edges. This is known as Scott number 1036 and a stamp from the Liberty issue between 1954 and 1968.
This is a very common stamp and is valued between 32 and 35 cents used (55 cents to 75 cents unused). Unused stamps are always worth face value and can still be used for postage, whereas used stamps are less valuable and tend to be traded in bulk based on weight rather than individually.
