Watch List notes:

Commemorative Medals, Archbishop William Sancroft (1617-1693) and the Seven Bishops, cast Silver Medal, 1688, by George Bower, bust of Sancroft right, in clerical robes and cap, rev medallic portraits and names of the Bishop of London and the six imprisoned bishops, 48mm (MI 622/37; Eimer 288), pierced and tooled, very fine; a second example, the obverse engraved with initials TW to either side of bust, 48mm, fine
It would be nice to speculate that the initials TW were in support of Thomas White, the Bishop of Peterborough, who is depicted on the medal's reverse.
