| Additional information |
Cook Islands issued a flurry of high-denomination bimetallic precious-metal pieces through the 1990s, many produced under licensing arrangements with foreign mints targeting the collector market rather than any circulation intent. The platinum-in-gold construction here is genuinely unusual — most bimetallic bullion of this period paired gold with silver, and the cost differential between a platinum core and a gold ring made these commercially precarious from the outset.
KM#306 is sparsely documented in auction records, suggesting either a very low mintage or concentrated private holdings that never reached the secondary market.
