It's probably just a filled-die error. That occurs when a bit of grease or dirt gets into the tiny recesses on a die that form the letters and numbers on a coin. Given that billions of cents are struck each year on high-speed presses, filled dies happen more than you might think, so they are generally not worth more than a few cents above face value.

...If you can read the date on the penny, it is not an unstamped penny.
The letter "D" found beneath the date of the penny indicates the coin was minted in Denver, Colorado.
Check that date again. There was no United States in the year 1111. The only penny that might have been minted that year was the British penny under the reign of King Henry I.

This type of error is called 'Off Center'. The more of the impression missing, the more it is valued, but those with a readable date and mint mark are the most valuable. If your penny (with no date) is an Indian Head penny it is worth $55.00. If it is a steel penny it is worth $45.00. Wheat pennies and Lincoln Memorial pennies are only worth $3.50.
