Button #1 just has two circles of dots for a back mark. Cannot identify. Also, do military buttons need a backmark to have been on a uniform, or be real military rather than just fashion buttons?
Button #2 has the Goodwins backmark but the others all have Pat July 27 1875. This button just has 75 for the year, no 18. Is it a correct mark? An older Mark?
I appreciate any and all help. I do try to research before I get on here and ask, I just hit dead ends on these.
