1.25" picturing the 1912 candidates with their offices and full names printed below the photos. Surface has light all-over wear but nothing at all that stands out and the wear is hardly even visible to the naked eye. There are also a couple of essentially microscopic pinpoint nicks mostly on the outer rim edge but again without magnification they are not at all apparent. Button displays totally clean and with perfect centering. Just a trace of age tone on the W&H backpaper. We offered this same item in Auction #180 with $2,500.00 opening bid. Rare.
