As a result, copper prices rose from £78/ton in 1785 to £200/ton in 1807. Adjusting for inflation, this is the modern equivalent of £20,470 ($24,850) per ton. But in reality, today's copper costs an average of $9,322/ton, showing just how much this demand drove up the price in a relatively short period of time.
