Unlisted Peter Kempson, 1/2d mule, c1795 (Noted as D&H Cambridgeshire 15c) Obv: A beehive and bees. Around the perimeter INDUSTRY HAS ITS SURE REWARDS. Rev: A stork standing, facing right. Around the perimeter PROMISSORY HALFPENNY . 1793 . The lower edge of the ground forms a smooth line. Edge: PAYABLE IN LONDON and engrailed struck over oblique milling.
The edge has every appearance of having been run through a Castaing-type machine twice: first with oblique milling as D&H 15a, then with a PAYABLE IN LONDON and engrailed, as D&H 15. Both dies were clearly used at the time, and Kempson productions frequently displayed both in different combinations. This is the first token that I've seen with one struck over the other - intentionally, or otherwise.
Better than very fine and previously unrecorded.
