When Does Collecting Banknotes Become More Than a Hobby?

Collecting banknotes can be a passing interest or as time goes on, an all-consuming hobby. After some years of buying banknotes for my own collection, a turning point was attending  a banknote auction in Warwick. The variety of notes, the ability to view the notes beforehand and the ‘thrill’ of the auction somehow got me hooked. For me, collecting notes is more than a passing interest. It is a hobby that has emerged into a small business that has allowed me to ‘meet’ other collectors who share the same passion for notes. I am not alone!
