That’s a great piece of history but, just to clarify, it’s an unofficial political propaganda medalet not a token.
Although the legend is in English, it celebrates victories for the Prussians (under Frederick the Great) against French and Austrian forces (under Maria Theresa) at the battles of Rossbach and Leuthen in 1757 during the “Seven Years War”.
Britain was one of the belligerents of the Seven Years War but didn’t participate in either battle, although it was sided with and providing financial support to the Prussians. Britain therefore had good reason to celebrate the victories and one contemporary account says that “the news of Frederick's victories was received with great rejoicing in England, and his portrait was to he found in nearly every shop and house.” Several variants of this medal were gleefully produced in large numbers.
