Prototypes
New pieces are constantly being developed and it can be difficult to get the size and weight just right, often there are a few prototypes a little over or under weight and/or other slight revisions were made. I typically offer these to frequent buyers first but check back here from time to time if that's something that interests you.
Prototypes like all Curio Bullion pieces come with a signed COA's, additionally these get stamped with a Star and P to designate them as prototypes.
