1775 MACHIN'S MILLS HALFPENNY -
The obverse die of this
variety was also used on:
1771 Vlack 4-71C
1771 Vlack 4-71D
This was the only use of the reverse die.
This is the only 1775 reverse in the Machin's Mills series. Great Britain
struck Halfpennies in 1775, so be sure to match the reverse die exactly.
