New Zealand's switch to copper-nickel for the florin in 1947 was a direct consequence of postwar silver shortages and British Commonwealth-wide pressure to conserve the metal. The 1947 issues across multiple Commonwealth territories were effectively simultaneous — a coordinated monetary adjustment rather than a local decision.
KM#10.2a is distinguished from the earlier silver-composition type by more than alloy alone; the copper-nickel planchets required adjusted striking pressures, and surface quality on these transitional issues can be inconsistent as a result.
