At top in 'in god we trust' is raised and looks like it was pressed to much forcing material upward...Also on the left it looks deep and affected the I and B in LIBERTY or maybe some doubling there..lost the reverse picture,,ill try to find it and add it but it is as good as the obverse..
I have seen it called a "ridge rim" because of the "ridge" inside the "rim", go figure!
I see it quite often on Zincolns and is caused by the outward flow/expansion of metal during the strike and the die being worn in a circumferential manner because of that. The die having a concentric circle of wear produces a corresponding raised area on the coin it strikes.
I don't know why it seems so prevalent on Zincolns, except for the fact that there are many more produced than other denominations and maybe die life is put to the test more than it has been.
