The question of provenance is always interesting. Because all the passes have names inscribed, the first thing to do is to check to see who might have the pass in question. If it is one of the "lost" passes, then other methods of provenance can be used -- for example, the actual alloy of silver will vary. What the buyer did, I do not know. You seem to assume that I was the buyer. That is not the case. I simply am an employee of the DSNGRR, working in the museum. I am interested in the passes, and one of my belt buckles is a replica of the pass, number 360. But by no stretch of the imagination would I be able, or interested, in buying an authentic pass.
