2 Pounds - Elizabeth II Hadrian's Wall - Pict Warrior, Silver Proof

Hadrian's Wall was begun around 122 AD following the emperor's personal visit to Britain — one of the few times a reigning emperor toured the province — and stretched 73 miles coast to coast, garrisoned by auxiliary troops rather than legionaries. The "Pict" designation is technically anachronistic for the Wall's construction period; the Pictish confederacy as a named group doesn't appear in Roman sources until the late 3rd century, roughly 150 years after building commenced.

Guernsey's use of the subject is a licensing arrangement rather than any territorial or historical connection to northern Britain.
