Watch List notes:

Halfcrown 1920 Davies 1672N struck in a hard nickel type alloy and weighing 12.43 grammes. There are 1924 trial nickel shillings, with a very rare example struck metrically weighing 5 gr. The 1672N Halfcrown listed here may also be a Royal Mint trial, when a complete elimination of silver seemed feasible. There appears to be an interesting 'privy' mark, introduced by a thicker down stroke to the 'D' of 'Dei' with the top serif of this 'D' being double struck. The border bead above is also oversized (wider). This would be an odd occurrence for any counterfeiter, especially on top of striking perfectly die-cut, but lightweight coins in this hard metal, and having excellent milling. a similar example was listed in Auction A151 6/12/2015 (Lot 2687, weight 11.92 grammes, realised £120 hammer price), the description then stating that only 6 of these examples were then known to the vendor Near Fine/VG a highly unusual type, comes with Colin Adams collection ticket

Estimate: 50-150 GBP
