1991 Penny Value: Price Chart by Grade & Mint Mark

In 1991 the U.S. Mint struck about 9.32 billion Lincoln cents for circulation: Philadelphia 5.17 billion, Denver 4.16 billion. That is 21% fewer than 1990. Among the 117 years from 1909 to 2025, 1991 ranks number 22 by total mintage (1 = most coins made), so it is one of the most common dates in the series. The scarcest 1991 issue by mintage is Denver (4,158,442,076); the most common is Philadelphia (5,165,940,000). Within the 1990s, 1991 ranks 8 of 10 years for mintage; the decade's high was 1994 (13.63 billion) and its low was 1992 (9.10 billion). Mint by mint: Philadelphia fell 25% from 1990; Denver fell 16% from 1990. Proof cents for collectors: 2,867,787 from San Francisco.

The mint mark, if any, sits under the date on the front of the coin. A 1991 cent with no mint mark was struck at Philadelphia and is the normal, common form for that mint. The letters you can find on 1991 circulation cents are D (Denver). Proof cents carry an S and have mirror-like fields; they came from collector sets, not from circulation.

• Cents from 1983 onward are copper-plated zinc (about 2.5 g). The plating is thin, so these coins corrode easily: bubbles, pitting or grey spots on a bright coin are damage, not a variety.
• True die doubling is rounded and separated; flat, shelf-like doubling is machine doubling and adds nothing. The mint marks guide has side-by-side examples.

Denver is the lowest-mintage 1991 issue (4,158,442,076 struck), so it is the mint collectors check first. Guide prices assume a certified coin; an uncertified, worn 1991 cent usually sells for less than the lowest figure above, and most circulated zinc cents are worth face value. RD means full original red copper, RB red-brown, BN brown; the color grade can multiply the price. How grade and variety turn into a number is explained in what makes a coin valuable.
