Successful Coin Collecting Format Adopted for Stamps, Free PSE "U.S. Design Numbers" Booklet

To attract new stamp collectors and assist novices who may be confused by a huge number of complicated, nearly-identical, minor varieties, Professional Stamp Experts (PSE) has created a simplified system explained in a free booklet offering, “A Guide to U.S. Design Numbers (USD).”

Guide to U.S. Design Numbers(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. 

These stamps represent the major designs, denominations and basic colors of the first century of U.S. stamps intended for use on letters or parcels.

The booklet contains a photo of each stamp and a cross listing of the USD numbers and their corresponding numbers in the Scott Standard Postage Stamp Catalogue.  The Scott numbers are used with permission of Scott Publishing Co., a subsidiary of Amos Press, Inc. 


“Beginners and even intermediate collectors can sometimes get frustrated and confused when confronted by 5, 10 or even 30 different varieties of stamps that at first glance all look alike. 

It’s the kind of confusion a novice coin collector might encounter when first confronted by hundreds of Morgan dollar VAM varieties. 

Varieties are wonderful, but you don’t have to be an advanced specialist to enjoy stamps or coins,” said Michael Sherman, President of PSE, the philatelic authentication and grading service that is a division of Collectors Universe, Inc. (NASDAQ: CLCT).

“The type set format gives collectors a new option to enjoy the hobby.”
