Most US stamps were printed and sold by the post office in whole sheets, and many people bought them with the intention of collecting or saving them for future generations. By definition, sheets are rarer than individual stamps of any given issue, because most sheets were broken up to be sold or used. Sheets of very common stamps are often not worth much more than face value, while sheets of rare stamps can be very valuable.
