Hi! I inherited these pieces from my father.
Unfortunately he never provided any information nor did I know enough to even ask, so I am trying to figure out what exactly I even have and if they are real. I appreciate any and all insight

Hi! I inherited these pieces from my father.
Are there any marks on the inside of them? Sterling, 925, initials or names?
Some appear to be Native made to me.
on the back of this buckle does it say:
“1977,78,79,80,81 Raintree Made in USA”
Thank you! Looks like there may possibly be some sort of marking…circled in the picture. Unfortunately as you can see these aren’t the cleanest so I can’t tell for sure what it may be…any advice on how to clean it up in order to see a marking more clearly?
I have a piece with “Sterling”, a piece with “S.B” and a piece with “SW” or “MS” depending on how you look at it
microfiber cloth and light pressure might knock off a few shades of the patina.
also note that this ring sadly is missing the tip inlay of the horses nose
also buckle is silver tone metal & enamel
