I hope someone better than I on button ID's comes along and is able to tell you for sure. Looking through my button references ( Tice; Albert; & McGuinn and Bazelon ) These two buttons seem to be post Civil War...... somewhere in the 1870's to 1893 area...... judging from the backmarks. But, again, I am no expert. Why don't you post them on americanrelichunters.com and see if all the Civil War relic hunters there can give you a better confirmation. Or, go to William Leigh's CW button website and see if you can find matches there.
