This has a curved die break on reverse running through top left of memorial and what looks like a break on Obverse in opposite direction, with some of it looking like it is incused with raised edges. I'm stumped!
The Reverse.. looks like a Neat Die Crack The Obverse.. looks to be just a Linear Plating Blister IMHO
@paddyman98 I did notice that the obverse line went under the I and N of IN instead of over like the reverse crack.
