Their grandfather passed away, then they found a trap door in his living room

The find

When John’s family finally opened up the trap door to the basement, after it had been closed for decades, their jaws dropped. Inside the basement they found a large collection of gold bars. According to a document on a table in the basement, there were over 1000 gold bars in this room. They had been exchanged for the contents of a certain barn, years ago.

They sent for an appraiser to get an idea of the value of this collection.
