Interesting Facts

Paper money was first introduced by the Chinese in 806 A.D. (Seemingly there was a severe copper shortage, and funnily they abandoned paper money again in 1455 (I guess they found some more copper). Notes didn't appear in Europe and America until the mid-1600s and it was another hundred years before paper money became common. It's strange that it ever did because, let's face it, paper currency is actually worthless.)

In the US, paper currency was created in 1862 to help pay for the Civil War. They were printed in $5, $10, and $20 denominations, redeemable in coins on demand. (All the notes were printed green, hence the nic name "greenbacks.")

Dollar’ is the most common currency name. (This is followed by ‘franc,’ ‘pound,’ ‘dinar,’ ‘peso,’ and ‘rupee.’)
