[QUOTE="GDJMSP, post: 3491777, member: 112"]That one's easy, a piece of finning that has broken loose on one end is the likely cause. Finning results from a few different causes. It can be a planchet is too thick or part of it is, die spacing is too close, or strike pressure is too high. But when it occurs, a tiny thin sliver of metal is forced up between the dies and the collar at strike. Usually, the fin or fins will get bent over flat against the coin's rim during the normal process of the coin being in the hopper, bagging, or packaging in some cases. And if it remains until released into circulation it'll happen quickly then. Or, it may even break completely off. But, it doesn't always get flattened out. On some coins it survives, and on some one end can break loose from attachment due to it flexing from contact with something. And when only one end remains attached - you get what ya see in that pic.[/QUOTE]
