All the gold mined in the California gold rush

Between 1848 and 1855, an estimated 750 tons of gold were extracted in California — worth over $75 billion in today’s prices ($3,115.05/oz).

If you were to squish it all into a single rectangular chunk, it would come out to 2.8 meters tall × 2.5 meters wide × 2.5 meters long as visualized.

The Data:

This figure is based on historical estimates from sources including American Bullion Inc. and corroborated by U.S. Geological Survey archives. At the time, the gold was valued at ~$16 an ounce (around $423M in 1850s currency), but at modern market prices (averaging ~$2,000/oz in recent years), the total haul would exceed $75 billion USD (inflation adjusted).

Note here that purity differed between different mines and that the visual depicts the size of the chunk based on a 19,320 kg/m density (pure gold).
