Why Not Try Stamp Collecting.
What better hobby is there to engage in if you are attempting to self Isolate or you are avoiding crowds and/or exposure to large groups of people?
Typically, stamp collecting is not so much about money but is very often driven by an interest in history, geography, art, and a need by many to "complete" a collection, very similar to owning a complete set of football/baseball cards for one team or season. Maybe you could take up philately as a new hobby or re-engage in one of the hobbies of your childhood.

What Is Stamp Collecting
According to the American Philatelic Society, "Stamp collecting" is the accumulation of material related to the payment of postage and the carriage of the mails. In addition to traditional postage stamps, many philatelists -- the fancy word for stamp collectors -- also collect covers, envelopes that carried mail. Some individuals also collect markings or labels applied to mail including postage meters. Others will even collect Christmas Seals, revenue stamps and other ephemera.
