Mint errors are some of the most exciting discoveries in coin collecting—and one of the rarest types is the wrong planchet strike. A famous example is the 1980 Jefferson Nickel struck on a Lincoln cent planchet, where the nickel design was accidentally stamped onto a copper penny blank.
Collectors love these “hybrid” mistakes, and depending on grade, they can sell for $325 to over $1,200! Let’s dive into what makes this coin special and how to spot one in your change. 👇
🔍 Key Features of the 1980 Nickel on a Penny Planchet
👉 Obverse (Front)
- Shows the standard 1980 Jefferson design
- “LIBERTY” and the date may appear off-center or distorted
- Copper color instead of nickel’s silver tone
👉 Reverse (Back)
- Monticello design still visible
- “FIVE CENTS” denomination remains but looks slightly compressed
- Coin is smaller than a normal nickel

|---|---|---|

✅ 4 Steps to Authenticate This Error Coin
1️⃣ Weight Check – Use a digital scale. Should weigh ~3.11g (like a penny), not 5g.
2️⃣ Diameter Test – Should measure ~19mm instead of the usual 21.2mm.
3️⃣ Magnet Test – Coin should be non-magnetic (normal post-1942 nickels contain nickel metal).
4️⃣ Edge Inspection – Look for a plain edge; smaller planchet makes this more obvious.
