Behind the door he found a dirty, smelly carpet and knew he wanted to get rid of it right away.
Upon further inspection, he realized it was some sort of strange safe locked up and hidden in the closet floor.
He pulled it open...
...And found a pile of bricks and lots of water damage
Under the bricks he discovered a time capsule from the 30s. There was a 1937 coin book — water-damaged on the outside, but all of the money inside was kept in pristine condition.
There were even more coin books.
And here is just a third of what was found inside the safe.
Diving back in, he found some old soaked dollar bills...
...and lots more coins.
Some coins were exceptionally rare and beautiful.
...a rusted box. Full of tools, perhaps?
Nope! In the decrepit box were piles of jewelry...
..bars of pure silver! Looks like he came into his own secret fortune, thanks to his amazing grandparents.
A user on the same reddit forum, who is a coin enthusiast, said that collectors would be very interested in the coins.
But perhaps even more valuable is the memory of his grandparents, who left behind all of these cool things.
