The current obverse image seems like it maybe skewed a bit from my end. So I'll refrain over analyzing it. Misaligned die strikes can produce a false rim as well as wide collar strikes or issues. Curious if obverse image is straight on or skewed? Also wondering what a straight on reverse image may suggest? Thanks, Doug. http://www.error-ref.com/wide-collar/ Edited by Halo1st 10/06/2018 12:54 am Report this Post to the Staff
Crazyb0 Rest in Peace 10197 Posts	Posted 10/06/2018 01:57 am Although the previous comments are OK, you have an overpressure strike. This causes more coin metal to be forced upwards, between the collar and side of the die below the rim offset. This when thinner is seen as a Rim Fin. This thick proto-rim is the excess forced metal. There looks to be a tilted die as well, which is associated with high pressure strikes... the increased downward distance can cause the tilt, which forces metal movement laterally(side to Side).

coop Bedrock of the Community United States 62064 Posts	Posted 10/06/2018 2:23 pm But what cause the Rim Fin? Probably a tilted die. With the die is tilted, it allows an area on between the collar and the die, to allow metal to rise on that area. The more the tilt, the more the rim rises. When the coins are wrapped or during circulation, it flattens them and they look like just like your coin. A premium if you can find them with the fin raised. Report this Post to the Staff
