After reading the article noted above it appears that you have post-1850 restrikes. Your examples probably circulated for many years. When I was stationed in Ethiopia (in what is now Asmara, Eritrea) in 1971 circulated Maria Thresa Thalers were easily available from street boys or in the marketplace. They were no longer used as currency by that time.
