Guess I should have done some research before typing...
Shortly before his death, fearing that he would be incarcerated as a result of Dewey's efforts, Schultz commissioned the construction of a special airtight and waterproof safe into which he placed $7 million in cash and bonds (the equivalent of $130,875,985.40 in 2019 dollars).[22] Schultz and Rosenkrantz then drove the safe to an undisclosed location somewhere in upstate New York and buried it. At the time of his death, the safe was still interred; as no evidence existed to indicate that either Schultz or Rosenkrantz had ever revealed the location of the safe to anyone, the exact place where the safe was buried died with them. Schultz's enemies are said to have spent the remainder of their lives searching for the safe. As the safe has never been recovered, treasure hunters have annually returned to look for it in the Catskills. One such meeting became the documentary film Digging for Dutch: The Search for the Lost Treasure of Dutch Schultz.
