Silver Unit Hadham Heart Ear

The Catuvellauni occupied territory roughly corresponding to modern Hertfordshire and beyond, and their silver units from this period reflect a tribe under mounting pressure — Caesar's two expeditions to Britain in 55 and 54 BC disrupted tribal power structures across the southeast, forcing renegotiated tribute arrangements and shifting alliances. The "Hadham" designation comes from the find concentration around Much Hadham in Hertfordshire, though these pieces circulated across a broader tribal range.

The "Heart Ear" subtype is distinguished by a specific motif variant used to differentiate die groupings within the ABC classification. At 1.2g these are appreciably lighter than earlier uninscribed British silver, reflecting a gradual debasement trend common across late Iron Age issues as tribal economies absorbed Roman commercial influence.
