What is a 1970-S Lincoln Memorial Cent Proof worth?
Age alone gives this coin a small premium, even worn. Sharp details and original surfaces push it higher. The exception is the 1970-S Small Date Lincoln Cent, which collectors pay a large premium for.
What would make yours worth more:
- Grade and, for proofs, strong cameo contrast
- A known variety for the date: 1970-S Small Date Lincoln Cent

Quick answers
- Is the 1970-S Lincoln Memorial Cent Proof rare?
- Not especially. The Mint made 2,632,810 for collectors. Most were kept in their original packaging.
- Where is the mint mark on a 1970 Lincoln Memorial Cent?
- On the obverse, below the date. Philadelphia cents have no mint mark (except the 2017-P, which is a Lincoln Shield cent). On this coin the mark is S, for San Francisco.
- How many 1970-S Lincoln Memorial Cent proofs were made?
- 2,632,810.
What to check on your 1970-S
- Make sure the mint mark really is an S. A worn or filled mark can be misread. It's what separates your coin from the 1970-S (691 million made).
- Look for the 1970-S Small Date Lincoln Cent.
- Judge the grade under good light. Wear first shows on Lincoln's cheekbone and hair. Doubled-die varieties from 1969-S, 1972, 1983 (reverse), 1984 and 1995 are the big money coins, so always check the lettering under magnification.
Proofs from 1970 come with and without frosted devices. Coins with strong contrast are labeled Cameo or Deep Cameo and are worth more.
The story of the 1970-S
No mint marks, special sets and famous doubled dies (1965 to 1973)
The Coinage Act of 1965 left the cent's bronze composition unchanged, but the Mint dropped mint marks from all coins from 1965 to 1967 to discourage hoarding. Collectors were offered Special Mint Sets with satin finish coins instead of proof sets. Mint marks returned in 1968. San Francisco resumed striking cents with an S for the first time since 1955.
Several doubled dies come from this period. The 1969-S doubled die obverse is rare and widely counterfeited. The 1971 and 1972 have doubled die obverses. The 1972 is one of the most dramatic, with strong doubling on the date and LIBERTY. The 1970-S has a scarce small date variety, also called the high 7. Copper prices were rising by 1973, which pushed the Treasury to look for a cheaper metal.
Elsewhere in US coinage in 1970
The last 40% silver Kennedy half dollars were struck. The 1970-D half was issued only in mint sets.
How to recognize it
The obverse keeps Victor David Brenner's portrait of Lincoln with the date and mint mark on the right. The reverse, by Frank Gasparro, shows the Lincoln Memorial in Washington, D.C., with a tiny statue of Lincoln visible between the central columns. E PLURIBUS UNUM is above the building and ONE CENT below. Look for the FG initials to the right of the steps.
