100th anniversary of mail order 8 cent stamp value

You're referring to the iconic 8-cent airmail stamp!

The 8-cent airmail stamp was indeed a significant issue in the history of mail order. Here's some background information:

• The 8-cent airmail stamp was introduced by the United States Postal Service (USPS) in 1918, as a response to the growing demand for airmail services.
• Prior to this, airmail services were limited, and mail was typically carried by rail or sea. The introduction of the 8-cent airmail stamp marked a significant shift towards faster and more efficient mail delivery.
• The stamp featured a design by artist Charles R. Knight, depicting a Curtiss JN-4 "Jenny" biplane, which was a popular aircraft used for airmail delivery at the time.
• The 8-cent airmail stamp was used for airmail services until 1932, when the USPS introduced a new 5-cent airmail stamp.

To commemorate the 100th anniversary of the 8-cent airmail stamp, the USPS might consider issuing a special commemorative stamp or a series of stamps highlighting the history of airmail services. However, I couldn't find any official announcements or confirmations from the USPS regarding such an issue.

If you're interested in collecting stamps or learning more about the history of airmail services, I recommend checking out the USPS website or visiting a local post office. They often have exhibits and resources available for stamp collectors and enthusiasts!
