Recovered from the wreck of the Dutch East India Company ship Akerendam, certified as such by Numismatic Guarantee Corporation with number 
6527908-011
 
On January 19th, 1725, the VOC ship Akerendam headed to Batavia (Jakarta, Indonesia) with 19 chests of gold and silver coins when it got hit by a snow storm and sunk off the Norwegian coast. Five of the chests were recovered, but the wreck was only further salvaged upon its rediscover in the 1970's. Of over 50,000 of the retrieved coins, the main type found within the 6,600 gold specimens was the 1724 Utrecht Ducat - a once extremely rare type. Also known as the "Runde Treasure", it's the largest coin treasure ever found in Norway.
