Abstract
One of the important assets that Gutenberg’s printing press gifted to modern political economies is the ability to print paper money. The common man usually thinks that paper money is the real money, while in fact it is only a promissory note promising the bearer of the note the payment of the same amount (in coins, if not in gold) by the Reserve Bank. In the past, however, governments did deny such payment in exchange of the notes and one government even made the holding of gold by the citizens as illegal.
