Final answer:
Pre-1982 pennies are worth more than post-1982 pennies due to their higher copper content, making them more valuable to collectors.
Step-by-step explanation:
The value of a penny is not determined by its year of minting, but rather by its composition and condition. Prior to 1982, pennies were made primarily of copper. These pre-1982 pennies contain a higher percentage of copper compared to post-1982 pennies, which are made mostly of zinc. The higher copper content makes pre-1982 pennies more valuable to collectors.
