Found a slightly off center 83-P Kennedy. I'm not sure if the amount off center is enough to be excited about, but I'm curious about the edge near 8 o'clock. There is a section of scalloped edge which appears to be aligned with the reeded edge of the coin. Anybody know what caused this?
Without seeing the reverse, I can't tell if it's really an off center strike. If it's like that on only one side, it's called a misaligned die, or MAD. The misalignment is not significant as it does not affect the devices of your coin. I can't speak to the scalloping of the edge, but I'm sure you'll get answers on that from others.
Correct on the MAD error description on this Kennedy - So I will add to what's going on with the rim. It's called a Double Rim or False Rim and is associated with reeded coins. Definition - quote "The second rim forms during the strike, when coin metal rises into the respective rim gutters of the obverse and reverse dies, forming the “design rim.” The design rim normally replaces the proto-rim. Certain striking errors (e.g., off-center strike, broadstrike, weak strike, die misalignment) can leave both rims standing." closed quote Here is an article written by Mike Diamond explaining it in full detail - http://www.coinworld.com/news/us-co...d-false-rims-arise-in-many-circumstances.html
Thanks for the explanations, I'm just starting to collect Kennedy Errors and appreciate all the insight you guys have!
