How much was john rolfe's tobacco crop worth?

The correct answeer to this opne question is the following.

In those early years of growing tobacco in Jamestown, Virginia, there was no money. The equivalent were "notes" that could be exchanged for goods. Virgina average an annually production of tobacco of 70,000 barrels or hogsheads, as they were called in those years. Every barrel weighted about 1,000 pounds. That was the standard measure. So in a year, Virginia farmers grew 70,000,000 pounds of tobacco.

Regarding the price of this cash crop, a pound of tobacco had a price of 2.5 cents per pound. So the profit in dollars in a year was $1,750,000.
