Hi pascoe, Your 455 on the left of your 3 Washington coil set, is not a 455. It's not a coil stamp. Fails parallel lines check (even without a gauge). To be an authentic coil. the top line and bottom line must run EXACTLY parallel to each other. Any variation, and it's not a coil. The top is cut by something other than a stripper, bottom is probably natural straight edge. Did you watermark this? If it's a single line, then it's a 425, if no watermark, it's a 463.
Edit: Before everyone jumps on me, having the lines parallel don't guarantee it is a coil either, but when the don't align, it is definitely not a coil.
