1982 Mid-Year Alloy Transition
When the price of copper exceeded the cent's face value in 1981, Congress authorized the switch from 95% copper bronze to copper-plated zinc:
Small Date vs Large Date Anatomy
Two distinct master hub dies were used in 1982:
- Large Date: The numeral '8' has an upper loop equal in size to the lower loop; the diagonal stroke of the '2' is completely straight.
- Small Date: The upper loop of the '8' is noticeably smaller and delicate; the baseline stroke of the '2' has an elegant upward curve.
The 1982-D Small Date Bronze Miracle
For 34 years, numismatic consensus held that Denver only struck Small Dates in zinc (2.50g).
In November 2016, an anonymous collector weighed a 1982-D Small Date on a digital scale and discovered it weighed 3.08 grams! Authenticated by PCGS, it stunned the coin collecting world and sold for $18,800.

Frequently Asked Questions
How many varieties of the 1982 Lincoln cent exist?
Officially, there are 7 common circulation varieties, plus 1 ultra-rare discovery variety (making 8 total): 1982 Large Date Bronze, 1982 Small Date Bronze, 1982 Large Date Zinc, 1982 Small Date Zinc, 1982-D Large Date Bronze, 1982-D Large Date Zinc, 1982-D Small Date Zinc, and the legendary 1982-D Small Date Bronze.
How can you easily tell if a 1982 cent is copper or zinc without a scale?
The 'Drop Test': Gently drop the coin onto a wooden or plastic surface. A 95% copper bronze cent produces a high, clear, resonant bell-like ping. A zinc cent produces a dull, flat, low-pitched click. However, using a 0.01-gram digital pocket scale is the only foolproof method.
What does a 1982 copper cent weigh versus a zinc cent?
A 95% copper (bronze) 1982 cent weighs approximately 3.11 grams (standard mint tolerance: 2.98g to 3.24g). A copper-plated zinc 1982 cent weighs only 2.50 grams (tolerance: 2.40g to 2.60g).
How do you tell a 1982 Small Date from a Large Date?
Examine the numeral '8' and '2': On the Small Date, the top loop of the '8' is significantly smaller and more delicate than the bottom loop, and the baseline of the '2' has an elegant upward curve. On the Large Date, both loops of the '8' are roughly equal size, and the diagonal bar of the '2' is completely straight.
Why is the 1982-D Small Date Bronze worth $30,000+?
In 1982, the Denver Mint only struck Small Dates in zinc. However, a tiny handful of leftover 3.11-gram copper blanks were accidentally fed into a Small Date Denver press. Only two genuine specimens have ever been discovered in the history of numismatics, making it one of the greatest pocket change discoveries of modern times.
Can you find a 1982-D Small Date Bronze in pocket change today?
Yes! Both authenticated specimens were found in everyday pocket change and bank rolls decades after 1982. Billions of 1982 cents were struck, and searching unsearched rolls with a digital scale remains an active hobby for Coin Roll Hunters.
Does a magnet stick to 1982 copper or zinc cents?
No. Neither copper nor zinc is magnetic. Neither coin will stick to a magnet. Only 1943 steel cents are magnetic.
