1952 D Planchet Error

[GrumpyEd]

Whoever the machinist is that did this is really good.

Probably a kid in a shop class, the pits might be from whatever they clamped it with to file the edge.
Sometimes you see a really clear pattern of clamp marks but on this one they probably rotated the coin a few times as they filed so it made a more random pattern of marks. Acid cents also could be used as dimes if they get the right size but I think this one came from the shop class not the chemistry class LOL

Not sure why the rev has no marks, maybe they clamped several together and made a few at a time or even clamped a dime with it and filed until the size matched.

Actually, these weren't too hard to make. Kids would sit on the sidewalk and scrape them on cement. Scrape and turn, scrape and turn until it was the right size!

Also due to the circ wear any file/sanding marks are probably long gone!!!
