Watch List notes:

James I, Royal Arms of England, copper roundel, shield within Garter, lion and unicorn supporters, lion atop crowned helm dividing I - R at top, 59mm., good fine and rare; another, smaller, of Charles I, 29.5mm., water-worn, fine (2)
The details of these roundels would have originally been enamelled, though neither show any traces. It is thought they were made to be placed at the centre of wooden tazzas.

Estimate: 100 - 140 GBP
