In celebration of Sea Shepherds 40th Anniversary, this limited edition commemorative coin was made from the propeller of their flagship vessel, the M/Y Steve Irwin. The propellor was made from 80% Copper, 9% Aluminium, 4% Iron, 3% Manganese and 4% Nickel. Size is 60x4mm. Coins are all handmade and may look slightly different from the coin showed on the images. Cased in a 80x80x20mm recycled cork box with 40th Anniversary print that also functions as a cradle. Due to the limited materials available from the propellor, only a limited number were made and distributed for sale amongst the various Sea Shepherd chapters around the world – get hold of your very own piece of Sea Shepherd history! Due to the natural fragility of cork, the corner has fallen off the back.
