Newspaper & Periodical Stamps
On March 3, 1863, an Act of Congress granted postal agents the ability to accept newspapers bundles, which would lead to the first US Newspaper and Periodical stamps two years later.
In the early days of the US Post Office, there was a rate of 1¢ per ounce on printed circular matter, making it expensive to mail newspapers and periodicals on a large scale. As a result, publishers turned to private express companies to deliver their printed material. But the Post Office wanted to get a share of the lucrative business.
