Broke open my first proof set awhile ago (1971), and I came across this guy. Know it's not post mint at all, because it came straight from the proof set. Has anyone seen this type of error before? Is it a rare error, or just your everyday proof? It appears some of the clad on the rim is missing for some reason. All help will be appreciated. Thanks! Here are the pics: Phoenix
Nothing is missing, all it is is that some of the clad layer, the silver colored part, got pushed down over the edge when the coin was struck thus covering up the middle copper layer. Sometimes it happens over the entire edge so that none of the copper layer can be seen.
It indicates that the edge of the hole in the perforated base plate through which the blanks are thrust was dull. So that would be a maintenance error. Kind of like failing to replace a worn die or a worn collar.
Cool, I guess I'll put it aside then. Thanks for the help. :thumb: Any specific name for this? Phoenix
Well, it sounds better than "Negligent Mint Employee Screw-up Proof Coin" and is easier to get on what little writing space there is on a 2x2! Frank
