Watch List notes:

Richard II, Groat, 4.56g, London, m.m. cross pattée, type IV, obv., new bust with crescent on breast, fleurs on other cusps except that at king's right shoulder, ricard dei gra rex angl z francie, saltire stops, rev., rev., n's of london unbarred, single and double saltire stops (N. 1321(b); S. 1681; Potter IV, dies 1/1, text, p.342 and pl. XIX, 11, this piece illustrated; Stewartby p. 261, IV), very fine and clear, extremely rare, possibly the best-preserved example known. F.A. Walters also published this coin at some length (NC 1904, pp. 10-12, pl. XIX, 15), speculating that the crescent, used as a mark on the early gold of Henry IV, might suggest a link with Henry's Heavy Coinage of which no groat is yet known. Ex J.G.H. Green Collection, 1902 and W.J.W. Potter Collection. (£6,000-8000)
