1987 No Mint Penny Error

Not a doubled die of any kind. Just one more of those lousy, messed up coins from the 1980's. Lots of coins from the 80's have that extra rim and what appears to be doubled letters and numbers but just lousy quality control at the Mint.

The proto-rim is caused by metal flowing outwards within the dies in late die stages, is what is known as Die Deterioration. This also has effect on digits as the 7, on the "rim" side, is deterioration of the face of the die, and known as DDD, Die Deterioration Doubling, which is NOT a hub doubled die. Much difference between hub doubling and Strike Doubling. One is the process of making the dies, the other is in using said dies.

Learn where to train your eyes to look. The edges fool you with Shadows, look more in the center or the tips of the devices.

It's Die Deterioration Doubling, cause by a worn die issue, from striking a ton of planchets. This was very common in the late 1980's and it doesn't carry any premium over face value, since it's normal wear and tear. It's a normal part of the minting process.

Thanks for teaching and I'm reading as I can, just a lot to process and honestly as a newbie I guess the excitement and rush is my problem
