And the rest...
1992 Canadian $20 Curtiss JN-4 Canuck silver coin, Numista link. 38mm in diameter, weight of 31.1g. 33,103 minted proofs. The old dude Sir Frank W. Baillie is not a pilot, not a war hero or plane designer but the knighted rich guy who put this biplane into production for the American army then for the private market. Making Canada some big cash.
