FoundThese buttons.... Maybe GC&SF railroad company Buttons( Mike Bearden thinks they might be ,but not sure ) mounted on a copper pin( I think that's what it is),,,not sure .I never saw anything like it .The Star (maybe a Teaxes Star) button has the letters.GC&SF between the star points. If anyone knows what it is please let me know. The home were I was searching was built in the 1840's.
