The first in a series of limited production collectible “Helmets in History” challenge coins produced for and sold by the Historical Diving Society USA. Each coin in the series will highlight a diving helmet with a positive impact on deep sea diving.
Every coin produced has the original HDS logo of an Augustus Siebe helmet on one side and the featured “Helmets in History” helmet on the reverse. This coin features Joe Savoie’s helmet.
These collectible coins are 1.75″ in diameter, are highly detailed, and will be a prized possession for years to come. Each comes in a soft PVC envelope.
Joe Savoie produced his first helmet in 1963, using an Italian motorcycle racing helmet as the shell. Savoie’s use of cams to attach the neck ring to the helmet became the eventual industry standard and is one of the main reasons Savoie is generally acknowledged as the originator of the modern free-swimming diving helmet.
