Only pic I could find with those was the 1931 on the pillar. at least they look a little like those. I wonder if any of those have ever been found in a Prima Agate Box. Mike, does the paperwork with slags call them Prima Agates or Just Primas. And Honey Onyx is a collector term, Peltier called them something. Sure wish I could examine that box. Those are neat marbles.
