Definitely die chips. Those areas are small and slightly weaker and tend to break away after a while. Since those areas are raised on a die, when it breaks away, it no longer is flush with the field and tends to be as deep if not deeper than the surrounding valley of the digit. When a planchet is struck, the void created by the die chip makes a raised area on the coin.
Thanks for confirming. I can never tell what it's supposed to look like when there's a die chip or a chip in the die gets smooshed into the coin. I can't imagine there be die chips without those chips getting stamped ito the coin every so often. Anyway, I'm surprised to hear that the last two are also die chips?? Cuz i Don't see any chips or extra bits but rather extra edges on top of the numbers, something like this, but not exactly....
