Coin and Paper Money Collecting/1980 penny


I 3have a 1980 penny that appears to be a double die reverse. In "UNITED STATES OF AMERICA" It's very noticeable and even. In "ONE CENT"  the "N" and "T" are clear as well.I cant seem to find any information on it.Can you tell me anything that can help?Thank's.


Without a photo, it's difficult to give an accurate answer. There are thousands of doubled dies, only a few are worth a lot of money. You may have a strike doubled coin, which is minor in value.

From "Definition: Mechanical doubling, also called machine doubling or strike doubling, a form of doubling which appears on a coin and is easily confused with doubled die strikes. On a true doubled die coin, the doubling comes from a mistake in the process used to make the coin die itself. In mechanical, or machine doubling, the doubled image results from mechanical issues during the striking of the coin, such as the coin shifting during striking, or the die itself being jarred out of position as a result of vibration or improper coin press maintenance. Mechanical, machine, and strike doubling are all considered by purists to be forms of damage, and are therefore not as collectible as a die doubled error coin."

Rather than go into a long description of how to tell the differences, I'm going to provide a link that describes this well and includes photos. Some experts feel anything that results in an error caused by the mint should be considered as collectible and sometimes valuable. The errors caused by strike doubling seem to be getting more notice.

Hope this helps.
