1460-1960 funfhundertjahrfeier Basel universitat silver medallion

Hi, has anyone seen this Swiss silver token? Numista gives it a 100 rarity. I’m trying to find out what it might sell for.

In all reality it is worth only what someone is willing to pay for it. Until you find that person, start at its bullion melt value. The Numista rarity index only indicates that no members of the Numista community claim to have a specimen of it but should not be used to indicate overall rarity in the marketplace.

I realize this is an old post but I have one of these. I've been wondering the same thing. Did you ever find any info?
