The government should be able to prove that, but IMO that isn't likely truth. More than likely some wealthy person buried stuff because they did not trust banks in the past.

If a robber stole than money you know they would have disbanded it all for cash over time, not bury it after risking their like to take it.

Maybe they were buried to hide them from FDR?

Fairly often a thief hides the stuff, then never makes it back to collect it. Most often because he’s either in clink or dead.
