50 Dollars - Elizabeth II 4th Portrait, Victoria Twenty Sovereigns

This issue recreates the Victorian-era Twenty Sovereigns denomination — a face value that never existed as a circulating coin in the British monetary system. The Reserve Bank packaged it as a collector piece tied to the 200th anniversary of Queen Victoria's birth in 1819, bundling the weight of twenty sovereigns into a single slug of 22-carat gold.

New Zealand's legal tender face value of fifty dollars is purely nominal — the gold content alone exceeds that by orders of magnitude at any modern spot price.
