Have you ever wondered where all that money in your wallet originates from? well, for starters, it is actually printed by The Bureau of Engraving and Printing in the US.
When Spenser Clacks invented the machine that could automatically cut down the paper to size before printing on huge sheets at a time, the revolution of printing started in the United States.
But before that was established in the 1862, it was actually printed by private banks. In present times, linen cotton blended in with blue and red fibers and made up into sheets are used to print money on so that it becomes hard for it to be counterfeited.
It is also known to take about a week for one such blank sheet of paper to be turned into money bills, 32 nos. to be precise.
