Can anyone tell me anything about these lead medallions? I found them in a joblot and I don't know much about them..they could be die trial strikes perhaps?? -- --
This probably doesn't help much, but for the last one I know Maria Theresa was the empress of Austria around the late 1700s. The middle one seems to say something about Prussia. All the writing seems to be German.
My guess is that those are plate examples of thalers. Someone else will come along shortly who won't have to guess.
