I don't have any idea on the first button. What is it made of? It looks like it might be old. The pin is not very old, mid1900's or so. The button with the eagle is a US great seal button. They started using these in 1902. I think your's is more 1950's or 60's and the next 2 buttons are blazer buttons. I have no idea on the buckle.
hi thanks for the response... the first button seems to be made of some extremely hard kind of multicolored plastic or plaster... I dont know, it's very hard though. It doesn't seem easy for the parts that have chipped away to have done it
