Philately is the collection and study of postage stamps and of materials relating to their history. People began collecting postage stamps soon after the first one was issued in 1840, and the scholarly study of stamps—their history and details like watermarks, perforations, and cancellations—followed within decades. Though their primary purpose is to provide proof of postage payment, stamps also serve as a sort of historic record. What was philately called before the term was coined in 1864? Discuss
