Scotland, Charles I, silver 12 shillings c. 1625-34, Edinburgh mint. 5.84 g. 

With a portrait by Charles Dickieson, which combines the previous portraits of James I on the Scottish coinage with the facial features of Charles, especially the pointy beard ! 

VF+, lovely old toning, a full round coin. Exceptional for the issue, and very rare thus. 

Spink 5542; Burns 3, Fig. 998 (same obverse die)
