here is an illustration of some coins with horses. we start with a Seventeenth Century token from Hatfield Hertfordshire which Robert Barnard used for his George and Dragon inn.
Next a copper jeton of Charles V as Duke of Austria and Burgundy.
We meet George and his Dragon again on a penny token from Upper Canada in 1854. then a silver check or medal from Doncaster Races dated in 1800. there are other pieces with D & G on them. Perhaps it was a betting firm. then back to George again on a 1935 silver crown to celebrate the Jubilee.
Staying with George but moving a few thousand miles east to Russia with a 1761 copper kopeck of Elizabeth.
