Check out what a appears to be a U-M class ring from 1950 up on eBay. It looks authentic. Obviously there is the wear, but also the Michigan seal (with no ‘The’ before ‘University of Michigan’ as discussed here.)
Hmm…looks authentic 1950, not @UMichFootball related but legit. Size 11, original owner was a hoss https://t.co/2WamnP62l9 #GoBlue pic.twitter.com/B1WySx8Dpn

Looks like it also features the facade of the Michigan Union which is a nice touch.
