Antique Odd Fellows Pin & Case

This antique pin is from Odd Fellows fraternal organization, and it has a modern locking c pin closure on the back of the 3 gold tone metal links at the top. There is a round piece dangling down that has a cut-out center with a star and flying bird. The back of the dangling piece is etched/marked "Mizpah Lodge No 10" at the top, "Millie Milhausen (and Pat appl'd for) at the bottom, and "July 1929" in the center. This piece is technically 4 years shy of antique, I admit. The piece seems to have inconsistent tones in the metal and I'm not sure what material content the piece has. The other pins that I've seen like this are 10K gold, but I couldn't find any marks to confirm that on this piece. The pin comes with a protective case, probably not original to the piece. It's in good condition except for a mark from what might have been a wet thumb grabbing the case. The pin has some wear and would benefit from a polish but is in decent condition overall. The tone change that would benefit from polishing can be seen on the bottom 2 points of the star and on the back. Pin dimensions: 36x23mm Case dimensions: 66x55mm Weight: 22.18g Love the piece but not the price? Make an offer! Please note, I'm not part of Odd Fellows or other similar groups, so please excuse any gaps in knowledge here!
