[DiogenesLamp]

Specie isn't trade, and if you keep spending it, you eventually run out.

But it does bring up a curious question. If the specie is coming from California and Nevada, then why is almost all the import money ending up in New York?

DiogenesLamp: "If the specie is coming from California and Nevada, then why is almost all the import money ending up in New York?"

Not all of it.
Thirty thousand pounds of gold worth several hundred million dollars today, went down on September 9, 1857, contributing to the Panic of 1857.
It was discovered and recovery began in 1988.
