Watch List notes:

BRITISH COINS, MILLED GOLD SOVEREIGNS, William IV (1830-1837), Gold Pattern Sovereign, 1830, by William Wyon after Francis Chantrey's model, second bare head right with coarse hair and flat topped, deeply engraved ear, w.w. incuse fully on truncation, nose points to second I in britanniar, legend reads gulielmus iiii d: g: britanniar rex f: d:, finely toothed border and raised rim both sides, coarse bead like border teeth, rev struck with inverted die axis, by Jean Baptiste Merlen, crowned quartered shield of arms, with the arms of Hanover as an escutcheon, seven heart semée, Irish arms with eight harp strings, crown with 13 pearls on each arch and five pearls each side of vertical facing upright, inner crown band with nine jewels, legend reads anno 1830 below, finer taller border teeth, edge plain (Bentley 394; WR 260 R5; Montagu 1083; Murdoch 440 (part); Nobleman 203; DM 178; S 3829B). Hairlined, reverse with one light rim abrasion, otherwise practically as struck and extremely rare.
It is interesting to see that the second bust rendition was used for this initial pattern dating from the year of accession in 1830. Most current coins from 1831 carry the first bust, whilst the second bust in currency for 1831 is extremely rare, being more wholly adopted from 1832. Therefore the chronology does not follow in reality as their referencing suggests. The second bust turned out to be the most prolific in this reign being used consistently from 1832 till the end of the reign. Both busts must have been used concurrently at times but the only reason they can accurately be called first and second bust is based on when they were phased out rather than when they were first used.

Estimate: £12,000-15,000
