Proof Platinum Noble Set
First struck in 1983, the Isle of Man's Noble was the first one-ounce platinum investment coin (shown). The Noble is also available in 1/20, 1/10, 1/4, 1/2, 5, and 10oz sizes. Platinum coins of the United States, Canada and Australia all followed this remarkable coin. Proof versions of these now-discontinued platinum coins are offered in sets containing the five smallest proof platinum coins.
