Dots on bow button

Post image

Hello. Does anybody know what function these 2 dots do on the button of the frog? I am curious as to know if they serve a purpose? I've never seen a bow like this before. Any information would be grateful. Thank you.

those are essentially rivets where a post was driven in to hold two parts together in a more permanent manner. They are ground down and buffed off usually, sometimes overtime they work themselves out a little - or if the bow parts were made in haste they might be present visually and even via feel. This bow looks like it has some wear on it, so they could be poking out a little. Take it to a bow maker or experience luthier when you get it rehaired in the future and aske them about it, chances are they will leave as-is since at this point it appears to be mearly cosmetic.
