1970 Penny (Lincoln Cent): Mintage & What to Check

In 1970 the U.S. Mint struck about 5.48 billion Lincoln cents for circulation: Philadelphia 1.90 billion, Denver 2.89 billion, San Francisco 690.6 million, San Francisco 2.6 million. That is 4% fewer than 1969. Among the 117 years from 1909 to 2025, 1970 ranks number 50 by total mintage (1 = most coins made), so it is a mid-range date for availability. The scarcest 1970 issue by mintage is San Francisco (2,632,810); the most common is Denver (2,891,438,900). Within the 1970s, 1970 ranks 9 of 10 years for mintage; the decade's high was 1979 (10.16 billion) and its low was 1971 (5.36 billion). Mint by mint: Philadelphia rose 67% from 1969; Denver fell 28% from 1969; San Francisco rose 27% from 1969; San Francisco fell 100% from 1969.

The mint mark, if any, sits under the date on the front of the coin. A 1970 cent with no mint mark was struck at Philadelphia and is the normal, common form for that mint. The letters you can find on 1970 circulation cents are D (Denver) and S (San Francisco).

• 1970-S cents come in a large date and a scarcer small date. On the small date the top of the 7 is level with the top of the other digits, and LIBERTY looks weak; on the large date the 7 sits lower.
• Cents from this era are 95% copper and weigh 3.11 g. A coin with this date that weighs about 2.5 g is a plated or altered piece, not a transitional error (zinc cents only begin in 1982). Small raised blobs or lines between letters, especially between the B and E of LIBERTY, are die breaks (collectors call them BIE cents); they are common and carry little premium.
• For any 1970 cent, check three things before anything else: that the date and mint mark are fully readable, that the surfaces have not been cleaned (unnatural brightness, fine parallel scratches), and whether any doubling on the lettering is true die doubling (rounded, separated) rather than flat machine doubling.

What a 1970 cent is worth depends on three things in this order: the variety (a recognised doubled die or transitional error is worth far more than a normal coin), the mint (San Francisco is the lowest-mintage 1970 issue), and the grade (an uncirculated coin with original red colour is a different market from a worn brown one). A normal, circulated 1970 cent from the most common mint is a very common coin; published price guides from grading services list values by grade and variety, and they change over time.
