Jersey's 4-shilling denomination is an anachronism that survived well into the modern era purely by local convention — the island retained its own unit system long after the rest of the British Isles had decimalised in 1971, and the 4-shilling piece represented one-fifth of a Jersey pound rather than fitting any mainland accounting logic. By 2000, these were essentially ceremonial issues; shillings had no practical purchasing role on the island.
The copper composition at this late date is itself notable — most jurisdictions had abandoned copper for base metal alloys decades earlier.
