Watch List notes:

Victoria, Jubilee coinage, a suite of three coins, all 1887 and each in glazed 9ct gold 'capstan' mount, the coins richly gilt, the reverses in 4 or 5 colours, halfcrown and florin with royal blue borders, shilling with red, Garter motto engraved on first and last, all three magnificent (3)
The maker's mark on first and last seems to be 'D..', the rest unclear but perhaps for Edward Durban & Co., Birmingham.
