This is a vintage Collegiate baritone tuba with three valves. It is a silver with patina that may be able to be cleaned off ? This musical instrument works as far as I can tell and is suitable for playing in a band or orchestra. It comes with old vintage case that’s not in good shape but protects it currently.
It’s is old and well traveled with dents and dings as pictured.

P.s. I am not sure how to clean it so I left it alone for someone who does so as not to damage it further.
