Is this a rare coin error? Should I send it in to be graded and put in a protective coin holder?
So I was down to the last few handfuls and i noticed something strange a quarter that was completely pure copper at first I thought it was fake then I saw that back side of the quarter a paper thin piece of metal I was thinking wow this is cool the quarter is literally split in 3 pieces both silver planchets and the copper core I thought that when coins were pressed these metals literally melt together well weld together from the pressure of being punched then flipped and punched from the other end or is it just once and both sides that sounds like it would be more accurate So I attached photos this quarter is from 1967 I didn't see a mint mark so thats about all I know ? Please let me know what everyone thinks? Value? Rare? Good find ? Thanks everyone for your time https://photos.app.goo.gl/5TSrc8SkeGoMVeZa8
