What is the value of a 1991 Uncirculated Double Die penny? And does anyone know how many exist?
Hey PokePlayer! It's flygon_frank from PokeGym,
I found what I thought to be one of these in a penny box a while back, and turned out to be a type of error called "machine doubling." I've never heard of another one, so that's really cool if you found one!
Here is more info about it: http://www.pcgs.com/Articles/Detail/3532
They still hold a few dollars value as "conversation pieces." But not as double dies.
Can you explain what Machine Doubling mean?
Ummm...you didn't read the article?
