Does anyone know about how to date these spectacles? I found them at an old tuburculosis sanitarium site that the only thing left is the concrete foundation. The site dates to the 1800s as I found an 1893 indianhead on that same site. These were about 4 inches deep just about an inch shallower than the indianhead. The ground is hard there so the sink rate isn't that bad. They are made of very thin wire and the surviving earpiece is curved. The lenses are made of glass and are more like magnifying reading glasses. Any help would be appreciated as I plan on donating them to the area museum.
