3.4.2 Examples of leaded brass alloy counterfeit one-pound coins

Lead is added to brass to improve its machinability. Similarly to the binary brasses it is very commonly used in general engineering. Counterfeits using this alloy have occured at a similar time and rate as the binary brass counterfeits.

A type XX counterfeit

COIN P15

This coin has been categorised as a type XX coin. The author has not been able to match the edge lettering to any of D.J.Cane's categories.

The main characteristic of this type is no cross on the edge lettering with a significantly large distance between the E and T of ET. The edge lettering characters do not have any serifs and the U and S of DECUS are of a characteristic shape.

This example was identified in Birmingham in 1999. It had a 1993 obverse and Ensigns Amorial reverse, that is a correct match. The alignment of the sides was incorrect. At least one other counterfeit of this type has been examined by the author.

The shape of the U and S of the edge lettering is unusual. The tool used to make the edge lettering appears to have had the bottom and top elements of the S made longer by a straight line punch or similar tool.
