The aim of this paper is to point out the commonalities and differences between the two currency reform approaches “100% Money” and “Sovereign Money”. The definition of “100% Money” was taken from Irving Fisher, the definition of “Sovereign Money” from Joseph Huber. The biggest commonality of these two approaches is the aim to end or to ease financial crises, the biggest difference is the way this money gets booked. This paper is interesting for students and teachers of finance, especially if they are experts in money theory.
