Hi all
I just recently looked these up and not really sure what they are or if they are collectable. It mentioned that the coin is missing a portion of the surface? if I am correct? would this be an example? I'm not exaclty sure what metal is used on the surface. this looks like normal copper corrosion to me, but thought I would ask to better understand this term. Or should I not worry about lamination errors while trying to build a collection. Die varieties are what interests me, but if it something someone collects and I run across one, then thats money in my paypal account for what I want, lol.
