Description

The third 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 the U.S. Navy Mark V diving 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.

The helmet design was created by a team led by Gunner‘s Mate George D. Stillson. It was the standard diving helmet for the US Navy from 1916 into the 1980s. The Mark V has become an iconic symbol of commercial and military diving. It is easily the most recognizable diving helmet in the world. During World War II, thousands of Mark V diving helmets were manufactured by Morse, Schrader, DESCO, and Miller Dunn.
