Howdy kiwipete - Welcome to the Forum !! Based on your description it sounds like you have a restrike issue of the Maria Theresia thaler. They are silver coins and are issued by Austria. But the coin has been minted with the same design and the same date ever since 1780. Their value is about $8 - $10. You can find out more about these coins here - Maria Theresia thalers
