It was the official currency for trade in Yemen, Saudi Arabia, and East Africa from the 18th century until the sixties. Traders loved it because its weight was stable and its silver content was guaranteed. Important to know: 90% of what's in the market today are *modern copies* minted by the Austrian Mint itself for collectors and investors. Original old copies are rare and expensive. To know if yours is original or a new copy, I need to see its back. Can you show me the second side? The back has an eagle with two heads.
