(Newport Beach, California) – A popular way to collect coins is the basis for a new system to attract new stamp collectors and assist novices who may be confused by a huge number of complicated, nearly identical varieties.
Professional Stamp Experts (PSE) of Newport Beach, California, a sister company of Professional Coin Grading Service, has created a simplified system for building a basic type set of U.S. postage stamps. PSE is offering a free, 56-page booklet that explains the new system.
Entitled, “A Guide to U.S. Design Numbers (1847 – 1947),” the new collection-building structure focuses on building a “type set” of 435 regular-issue U.S. postage stamps.
