Generally, the weight of a US coin depends on its denomination and the era it was minted, as the composition and, consequently, the weight have changed over time.
Here are the weights of currently circulating US coins:
- Penny (1¢): 2.5 grams
- Nickel (5¢): 5.0 grams
- Dime (10¢): 2.268 grams
- Quarter (25¢): 5.67 grams
- Half-dollar (50¢): 11.34 grams
- Dollar coin ($1): 8.1 grams
- Pennies issued before October 1982 weighed 3.11 grams.
- Quarters minted before 1965, composed of 90% silver, weighed 6.25 grams.
- Half Dollars also saw weight changes, weighing 12.5 grams in 1964 (90% silver) and 11.5 grams from 1965-1970 (40% silver).
Understanding these weight variations is particularly important for numismatists and collectors, as it can help them identify rare or error coins.
