Hi there, in an effort to learn about different errors, can someone tell me what's going on with this penny? It has a weird bumpy texture, a strike through error in "liberty", and severe Machine Doubling on the front and back. What would cause this? I know the penny is just a novelty and not worth anything. Kinda cool though.

Not seeing MD,maybe some DDD. The texture is from zinc dust being trapped between the zinc core and copper plating. LIBERTY looks like a struck through grease.

So does DDD produce the same shelf doubling that Machine Doubling creates? I see it on almost every letter and along side the monument on the right side on the reverse. It's my first novelty coin that I found, so you'll have to excuse my excitement.

Does this mean that the penny was minted when the die was at the end of its life and was about to be replaced?

DDD is Die Deterioration Doubling. See my tutorial on Die Deterioration Doubling, for more information, in my signature box below. Your coin also has a very minor struck through grease issue and a plating issue. Not a keeper.

Mild DDD and a severe case of zinc debris.

Cool! Thanks everyone. I know there's no value to it, but I'll hold on to it for educational purposes. I like that it's funky and one of the first out of the ordinary coins I found.
