This is an 1808 calendar medal made by Kempson and Kindon of Birmingham. Interesting brass item, but it must have worn a hole in a few pockets. First time I've ever seen one of these.
A bit of history about these and Kempson & Kindon
Peter Kempson struck single year calendar medals from 1796 to 1826, on his own as P. Kempson (1796-1801), in partnership with James Kindon as Kempson & Kindon (1802-1810), with his son as P. Kempson & Son (1810-1824) and finally as Kempson & Co (1824-1825). Peter Kempson was a Birmingham button-manufacturer who also produced a vast array of tokens for collectors.
