Anybody know what era these are from? My guess is late 1700s early 1800s.
Thank you for your response, however I respectfully disagree to your estimated post 1882 dating. It is my understanding that Krementz's machine mass produced a stamped out single piece cufflink. This cufflink is two pieces connected by a chain loop, much like the designs of late 1790s into the early 1800s.
