It's unusual to find either an engine plant stamp or an assembly plant VIN stamp where the characters all have absolutely equal depth and definition; there were many variables involved in the length and wear of the individual dies, angle at which the holder was held, direction of the hammer blow, etc. Many restamps, however, are "perfect".
