Except for the year and the unusual spelling of Edward, you are describing a sterling silver Crown (Five Shilling) coin. The man on the horse is possibly St. George in the act of slaying a dragon. The only Edward VII Crowns to be minted were dated 1902, the year of his Coronation. The coin/token/medallion is most likely a souvenir from the 1908 London Summer Olympic Games which were opened by King Edward VII. They were produced in quantity and possibly have very little value.
Gold is currently £830-a-Troy Ounce (31.1035 gms). In 1911, there were three gold coins issued under the reign of George V (Edward VII had died in 1910). The coin you have (probably the FIVE POUND PIECE), if dated, 1911 could be worth from £1,200 - £2,500 depending on condition. Check to see that the monarch is George V and not Edward VII.
Your coin is a medallion probably rare. Where did you find the coin?
