Georgian/Victorian Period Silver Shoe Buckles Thrift Shop Find

Hi, All! These formerly FILTHY silver shoe buckles were bought today from a local thrift shop for 1 Euro ($1.19). They looked like pewter and I think that is what the thrift shop personnel thought, so tossed them in a small box in the display case! I found the sword mark....This Dutch silver sword mark dates these buckles to between 1814-1904. I think they are early Georgian period. My hopes of finding out the name of the silversmith/company, however, are pretty much ZERO.

Thanks for stopping!
