Coin and Paper Money Collecting/1983 penny


1983 d double mint error
1983 d double mint err  
Was wondering if you knew anything about a 1983 d penny with a double mint mark? I've searched and no one claims one , I did find a photo of one where the d is struck 2 times. Mine looks exactly like the photo.  Thanks for your time.


From the photo, it appears you have a machine doubled mint mark. Other features on the coin may also appear doubled. See:

The mint changed the manner in how mint marks were put on coins. They used to be punched into the die by hand. They are now made as part of the die, so double mint mark errors are as thing of the past. Your date falls into that category.

Basically, strike doubling is flat, and not two distinct images, where die doubling is raised and distinct. 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. See:

I've provided two links for you to see what type of other non-error coins exist.
