Human nature of folks is to bury money .. hide it . Back in the day with run on the banks banks going broke , people lost all there money. men going off to war may have , and our government passing laws for folks to turn in ther e silver and gold for worthless paper money .
In 64 removing silver or anything of value other then copper from our currency .
Many also migrated from other countries and lived threw wars or had rulers that were tyrents and took the people's money. They have been tricked before so never again .... So they hide it! They have had there land taken away or were not aloud to own it . It's a nest egg . Even family may not be trusted. Silverware or tea sets and platters , gold rings and diomonds .
A jar of coins , a piggy bank in the flower bed hiding from your big sister, a little stash of some sort .
Hope this helps .
