    Found this quarter in my pocket change a few months ago and have been try to learn more about its uniqueness. I think it is an experimental planchet intended for the Sacagawea. One of the errors that I don't get is there isn't supposed to be and copper color on the rim ridge area. I am confused and need someone to throw me a bone. Just need to know if it is worth anything and if so what shouldnI do...any help is appreciated.
    Thank you

    Someone shaved the edge off. Not an error, or an experimental planchet. Just damage.

    It's not worth keeping IMO

    It does not look like an experimental planchet as GH#75 said.
    What is the weight?

    EDIT:
    It could also have been spooned. This happens when someone repeatedly hits the edge with something until it is flat.

    Whatever it is, I don't think it's ancient. ;)

    I need to get a new scale that goes to the hundredths. The weight bounces between 5.7 n 5.8

    I didn't even notice that this was in the ancient's forum.
    The experimental planchets were considerably heavier than a standard Quarter. (5.67g) The mint has a tolerance of a tenth or more. I am not sure of the exact number. All of them had a manganese content, either with or without a copper core. Yours has the look of a standard quarter.
    The planchets were being tested with quarter dies, because the dies for the Sacagawea weren't finished yet.

    It was posted in the Ancient Coins section. I just used my magic moderator wand to move it over to the US Coins section. Presto! It is fixed.

    I don’t think so. Spooning would have had a much less smooth result, probably. I concur with your first comment. The edge was “shaved off” abrasively with some kind of grinding/sanding equipment. Why, we will maybe never know.

    You can plainly see the copper-nickel clad layers on the edge. I do not believe there were any clad “sandwich” experimental planchets for the Sacajawea dollars, were there? If so, that would be news to me.

    Unless I am mistaken, this is a regular Georgia quarter with mild environmental damage and a ground-off edge. The latter is interesting, but it is post-mint damage, unfortunately.

    Welcome, you are in the right area. Your coin has PMD (Post Mint Damage), including the edge. Thanks for the post and good luck.

    Looks like a washing machine coin to me. They get that type of edge.
