British, Scotland, Mary, first period, AR medal, her engagement to Francis, 1553

Once considered a pattern testoon, the weight and the use of the FM monogram before their marraige suggests instead that this piece is medallic. It is possibly an official jeton manufactured by the Paris mint for use within Mary's French household. 

VF+, old tone, chased fields, edge damage, possibly ex-jewellery. Extremely rare.
