Watch List notes:

Five Pound Crown, an undated (1997) pre-production obverse uniface trial in lead, the obverse portrait similar to the adopted bust used from 1998 onwards, the obverse differs by being undated, the lettering is of a slightly less refined style, and with slightly larger IRB initials below the bust. The date of production can be ascertained by the existence of a silver coin struck from the same dies which bears a hallmark from 1997. The edge has the appearance of two pieces of metal joined to create a 5mm thick flan weighing 61.45 grammes, EF, a most unusual piece, from the Ian Rank-Broadley personal collection

Estimate: 250-500 GBP
