The question of what year is the most expensive penny refers to a single 1943 copper Lincoln cent that set a record at auction. This coin is exceptionally rare because it was struck on the wrong planchet during wartime metal shortages.
Understanding its background, specifications, market performance, and preservation standards helps collectors gauge value and risk when pursuing this iconic error coin.
1943 Copper Penny Overview
The most expensive penny is the 1943 copper Lincoln cent, created when the Mint accidentally used bronze planchets in a steel-planchet year. Only a handful are confirmed to exist.
| Year | Mint Mark | Metal Composition | Known Specimens | Record Sale Price |
|---|---|---|---|---|
| 1943 | None (Philadelphia) | Copper (Bronze) | Approx. 10–15 confirmed | Over $1.7 million |
Production Errors and Rarity
How the 1943 Copper Error Occurred
During 1943, the U.S. Mint switched to steel cents to conserve copper for World War II. A small number of bronze planchets remained in the press feeders, leading to a tiny mintage of copper-dated strikes.
Grading and Authentication Importance
Professional grading from PCGS or NGC is essential. Verified examples receive numeric grades, which directly influence price more than the date alone.

FAQ
Reader questions
How can I verify whether a 1943 cent is truly copper and not plated steel?
Use a calibrated scale to check weight (copper cents weigh ~3.11 g versus ~2.7 g for steel) and verify with a magnet (steel is magnetic). Confirming authenticity through PCGS or NGC is strongly recommended.
What grade do collectors typically seek for the most expensive penny to maximize value?
High-grade collectors target Mint State 64 to 66, with red or red-brown coloration. Each point on the grade scale can significantly affect market price.
Are there other valuable years besides 1943 for copper pennies?
Yes, 1944 steel cents struck on bronze planchets and 1955 doubled-die cents are also highly valuable, though they involve different error types and price ranges.
How often do 1943 copper cents appear at auction, and is ownership regulated?
They appear infrequently due to low survival numbers. Export and sale may be subject to heritage laws, so verify compliance before purchasing.
