The 2009 Spiegel Grove Medallion was created to commemorate the sinking of the USS Spiegel Grove as an artificial reef and used as a permit for diving throughout 2009. They were used to help pay for the sinking of the ship and they are rare and highly sought after by collectors. These medallions are difficult to find due to their limited release and the passage of time since their creation. However, the Museum of Diving History holds a collection of these unique pieces and the sale of them are actually donations to our nonprofit.
