JCro57 ... I was referring to SPP's coin that he has in 2 separate holders, not the one that you posted..
Joe, it can go into two different holders, or a 2-pc. holder, but it won't be called a mated pair. It's a detached outer clad layer now.
Awesome. Thanks for the knowledge, as always. I thought "mated pair" meant any two coins that went together, like this one, split planchets, brockages, etc.
Ok. I received it, and it rolls around inside the slab, which means it is making contact with the copper core. I think I now have to submit it to put in separate holders.
