What is a 2010-S Lincoln Shield Cent Proof worth?
Age alone gives this coin a small premium, even worn. Sharp details and original surfaces push it higher.
What would make yours worth more:
- Grade and, for proofs, strong cameo contrast
- A die variety or minting error
For market prices, check recent sold results for certified coins in the same grade.
Quick answers
- Is the 2010-S Lincoln Shield Cent Proof rare?
- Not especially. The Mint made 1,689,364 for collectors. Most were kept in their original packaging.
- Where is the mint mark on a 2010 Lincoln Shield Cent?
- On the obverse, below the date. Philadelphia cents have no mint mark, except the 2017-P (struck for the Mint's 225th anniversary). On this coin the mark is S, for San Francisco.
- How many 2010-S Lincoln Shield Cent proofs were made?
- 1,689,364.
What to check on your 2010-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 2010 (2 billion made).
- Judge the grade under good light. Modern zinc cents are judged on luster and eye appeal; spots, scratches and plating flaws lower value. Proofs are graded for cameo contrast (CAM / DCAM).
Proofs from 2010 come with and without frosted devices. Coins with strong contrast are labeled Cameo or Deep Cameo and are worth more.
The story of the 2010-S
The Union Shield arrives (2010 to 2013)
In 2010 the Lincoln Shield reverse by Lyndall Bass replaced the Memorial reverse. The shield symbolizes Lincoln's preservation of the Union, with E PLURIBUS UNUM on a banner across the top and ONE CENT on a scroll. Production started below 2 billion at Philadelphia in 2010, then climbed steadily to more than 3 billion by 2012 and 2013.
The 2010 uncirculated sets were the last to include satin finish cents, which makes that version a one year type for the Shield design. Philadelphia and Denver coins from these years are common, while proofs were made only at San Francisco. Collectors look for doubled dies and die cracks, but the most important factor is surface quality, since copper-plated zinc can spot or discolor easily.
Elsewhere in US coinage in 2010
The Union Shield reverse replaced the Lincoln Memorial on the cent. The America the Beautiful quarters began, honoring a national park or site in every state and territory.
How to recognize it
The reverse shows a union shield with a scroll reading ONE CENT across it, with E PLURIBUS UNUM above and UNITED STATES OF AMERICA around the top. The shield stands for Lincoln's work to preserve the Union. The obverse keeps the Lincoln portrait, with the date and any mint mark to the right.
