1980 Jefferson Nickel Struck on Cent Planchet, PCGS MS-64 RB, Offered in February 2026
A 1980 Jefferson nickel struck on a one-cent planchet, graded PCGS MS-64 RB, was offered by GreatCollections in February 2026, according to a CoinWeek report published on February 19, 2026. The auction was scheduled to close on February 22, 2026.
Correction (Oct 13, 2026): We rewrote the headline, summary and body to match the source, a CoinWeek report of February 19, 2026, about a lot offered by GreatCollections in an auction scheduled to close on February 22, 2026. We removed an unsupported account that a collector discovered the coin decades later by its weight, corrected the statement that 1980 cent planchets were copper-plated zinc (the source says cents before mid-1982 were a copper-zinc alloy), and removed claims about Mint quality-control failures and an investment recommendation. The previous headline was "1980 Jefferson Nickel on Cent Planchet: PCGS MS-64 RB Reveals Mint QC Vulnerabilities."
This article is based on a CoinWeek report published on February 19, 2026. It describes a lot in an auction scheduled to close on February 22, 2026; it is not breaking news.
A 1980 Jefferson nickel struck on a cent planchet was offered by GreatCollections. The coin is graded MS-64 RB by PCGS. The auction was scheduled to close on Sunday, February 22, 2026, at 7:57:42 PM.
What the error is
CoinWeek calls this type of piece a major off-metal error. A blank intended for a one-cent coin was struck with nickel dies. As a result, the finished piece carries the Jefferson nickel design on a smaller, copper-colored cent blank. According to the report, the coin appears undersized, the design looks compressed, and portions of the outer lettering are often cut off.
How it happens
The report describes how the error can occur. Cent planchets can mix with nickel blanks: leftover cent blanks may remain in a hopper from an earlier run, or cent blanks may slip into a shipment prepared for nickel production.
A cent planchet measures approximately 2.1 millimeters smaller than a nickel planchet, so it does not fit securely within a nickel press collar. When the dies strike, the collar cannot fully restrain the metal and the planchet spreads outward. The coin often looks broadstruck or distended, and design elements near the rim, such as "IN GOD WE TRUST," may be incomplete or partly missing.
Why few escape the Mint
The U.S. Mint uses riddling devices, screens with holes sized to catch pieces of the wrong dimensions, to keep wrong-size coins from leaving the facility. According to the report, most off-metal strikes therefore never enter circulation. On rare occasions, a coin slips through and may mix into standard bags of nickels.
Planchet types
Collectors classify these errors by the cent blank used, the report says.
- Copper cent planchets (pre-1982): Before mid-1982, cents were made of a solid copper-zinc alloy and weighed 3.11 grams. The 1980 coin falls into this category. - Zinc cent planchets (post-1982): After 1982, cents were copper-plated zinc and weighed 2.5 grams. If the plating fractures during the strike, the silver-gray zinc core may show. - Steel cent planchets (1943): Pieces struck on zinc-coated steel blanks from 1943 are gray and respond to magnets. The report calls these the rarest examples.
The report explains that the Red-Brown (RB) designation reflects original red copper color that has begun to turn brown.
Price ranges cited in the report
According to CoinWeek, Jefferson nickels struck on cent planchets from common dates such as 1978 and 1980 typically sell between $350 and $500, and high-grade examples often exceed $1,000 to $1,700. These are the report's general ranges, not the result of this auction.
