Some sources estimate there are about 2-3 million freemasons spread all over the world. They are organised in Lodges and meet in regular meetings at fixed places. Freemasonry membership requires that a candidate believe in a Supreme Being, however the candidate can choose his own interpretation of this believe. So, Freemasonry accepts members from a wide range of faiths. Because their extensive use of symbols and rituals, lodges are often distrusted and associated with conspiracies. Actually, their main preoccupations remain charitable work within a community in a morally responsable way conform their beliefs.
Besides these activities, lodges manage their property and assets; and they may own and share its premises. Like any other business, they will have operations to manage such as dealing with expenses and proceedings, charity funds, membership administration, accounting, etcetera. And that is where our hobby comes into the picture. Masonic organizations have left us share and bond certificates.
