Scott Catalog News by Charles Snee
Another month has passed, and that means it’s time to reveal another batch of new Scott catalog numbers.
The editors of the Scott catalogs each month assign catalog numbers to new issues from the United States, United Nations and postal services from around the world.
The new Scott numbers detailed here are for recently issued U.S. stamps. New Scott numbers for worldwide stamps are given in the Scott New Listings Update in the expanded monthly issue of Linn’s Stamp News.
Included in this month’s listings are Scott numbers for the 10 commemorative forever stamps featuring wire sculptures by artist Ruth Asawa and the five commemoratives celebrating innovations in computing, biomedicine, genome sequencing, robotics and solar technology. Also Scott official are the quartet of Thank You stamps and the single commemorative celebrating the centennial of women’s suffrage in the United States.
What do these Scott numbers signify? In short, each stamp’s listing in an upcoming edition of the 2021 Scott catalogs.
Having these numbers handy will allow you to easily locate these stamps in the Scott catalogs and learn about their production and values.
Now that you have some context, here are the new U.S. Scott numbers:
