Scrooge McDuck’s iconic Money Bin from (the original) Duck Tales.

Not included: three cubic acres of cash.

The actual volume of money that can reasonably fit in this is more like 38x30x50 = 57 000 cubic meters, equivalent to around 23 olympic swimming pools. A liter of coins is worth something like $1000, so if it was filled with coins that would be 57 billion (57 000 000 000) dollars. The richest people in the world today are actually richer than this.

This is a fairly simple model with just a diffuse texture. No normal map since I imagine the building to be completely smooth, made out of some extremely strong blast-proof material.
