OMG! Looks like this on both sides. Is it real? The roll was OBW (original bank wrapped). The oval shape was just from the angle I took the photo.
Is it copper? Looks silvery in the pic. Anyway it's a blank upset planchet. If it's copper, it's worth a couple of bucks. If it's silver, quite a bit more.
They upset the rim prior to striking, but the retaining collar adds the reeds if applicable, and keeps the planchet the proper size so that the metal is forced into the crevices of the die and not out the edges.
Yes but you are the only one who does and you can't prove it to anyone else so it just becomes a regular generic planchet.
Year and mint specifies when and where a coin was struck. Your planchet was never struck and therefore, isn't a coin, and doesn't need a mintmark or year.
