I have this stamp and was trying to determine which one I had.
How can you tell a Coil from a Flat Plate from a Rotary manufactured/printed stamp?
Thanks,

I believe all coil (perfs on 2 sides) versions where Rotary Press. The sheet version was available in both. Rotary press stamps used curved plates so the actual printed image is slightly taller or wide than the flat.
