Vintage Barry Goldwater for President Political Button AND Gold Tone Brooch Pin

Vintage Barry Goldwater for President Political Button AND Gold Tone Brooch Pin Button is appx 1 1/2" wide and I don't see any issues with it...no rust, etc. The Goldwater brooch is 2" across, The clasp works well. The only issue I see with it is that the gold tone has worn off of the top of the letter "t" on the back and top of the front. It's much more visible in the pictures than in real life.
