Came across this generally unremarkable coin yesterday. The "COL" on COLOMBIA caught my eye though. Does this look like a struck through grease error to anyone else? Or is there another striking error that could cause this?
Took me a few, I think I see what you are seeing. Better photos would help. Are you still here @GeorgeM ?
This is a minor error, You can search this site and see which better fits your coin. http://www.error-ref.com/
