10 Pounds - Elizabeth II 19th Century Monarchs

Guernsey's commemorative program in the early 2000s leaned heavily on British royal history as a revenue-generating exercise, and this oversized crown-format piece is squarely in that tradition. The island's minting authority had no independent monetary relationship with the monarchs being honored — the series is curatorial, not constitutional.

At 155.52 g, this is a five-ounce silver piece, a format that gained traction in the late 1990s as collector demand for substantial silver grew. KM#116 is not a scarce issue by any meaningful standard.
