Plate Block

Philatelists often collect plate blocks, which are sheets that designate the serial numbers of stamps. Prior to the advent of digital accounting methods, plate blocks were essential to controlling the production of stamps. You can find plate blocks from around the time of the printing of the earliest editions of self-adhesive stamps. Even Great Britain's Penny Blacks and Penny Reds, for instance, contain plate number coils.The United States implements a modern take on the plate block technique. The postal service puts the number and the printer's name next to each other. When stamps come in large blocks, printers often create multiple plate numbers for their sheets. Philatelists go to great lengths to collect all plate numbers within particular series. There is a huge diversity of plate blocks. Each country and sometimes each postal locality maintains different standards.U.S. stamp collectors may look to the Scott Catalog to locate certain plate block species. However, even the Scott Catalog doesn't include all essential plate block information for every U.S. stamp printing. A true plate block collector might want to create albums devoted to variations on plate blocks and their number coils.Plate block numbers may be obscured or deteriorated on certain old stamps. While it may be tempting to clean off these stamps to get better glimpses at their plate blocks numbers, don't do so unless you have expert equipment at your disposal. Stamp rehabilitation requires practice and care. A seemingly delicate plate block number recovery can lead to the degradation of valuable stamps.
