Belvedere emblem identification

Hi, Guys.

I know zilch about the Belvedere, but I have two matching Belvedere emblems that I got in a toolbox from my Grandfather-in-law. He passed before I could ask him about the emblems. I tried looking on the web but am apparently not doing a good job. It looks like they may go on '55 fenders, but I really don't know. I can't find pics of many that have the loop on the B.

Any idea what year(s) they come from and if they have any value? They are dirty but in good condition.

Thanks!
Jeff
