Coins that did not fall directly under the stamping 'dies' are called "off-center"coins.
Here is an example of such an error where the coin involved is a 19th century Flying Eagle cent, the first modern size penny issued.
Previously, pennies were copper and the size of a quarter.



Off center errors occur in all denominations and also in the early years of U. S. coinage.
A few examples from the archive follows:

2 cent piece 3 cent in Nickel 20 cent piece
Buffalo Nickel 3 cent in Silver Shield Nickel .... Also See Shield Nickel with Rays
