Silver Unit Thatcher's Sister / Late Whaddon Chase Type

The Whaddon Chase series takes its name from a hoard of around 80 gold staters found in Buckinghamshire in 1849, which established the typological framework for this entire coinage group. The silver units associated with the Late Whaddon Chase tradition represent a fractional currency operating alongside the gold, likely used for smaller-scale exchanges within Trinovantian territory — the tribe that controlled much of modern Essex and Hertfordshire before and during Caesar's two British expeditions of 55 and 54 BC.

The "Thatcher's Sister" designation is a modern dealer nickname, not an ancient classification — a reminder that Celtic numismatic nomenclature often reflects find circumstances or whim rather than scholarship.
