Fireball XL5 Thermos Value Guide

The 1964 Fireball XL5 Thermos is a premier example of 1960s 'Supermarionation' memorabilia, featuring vibrant lithographed artwork from Gerry Anderson's iconic British sci-fi series. Produced by the King Seeley Thermos Company, this metal vessel remains a highly sought-after piece of space-age Americana that originally accompanied the matching lunchbox set.

What Is Fireball XL5 Thermos Worth?

The typical price range for Fireball XL5 Thermos is $50 - $100 based on recent sales. However, values can vary depending on the item's condition, rarity, and other factors such as:

• Physical condition of the lithography, specifically looking for the absence of rust, scratches, or 'flea bites' in the paint.
• The presence of the original internal glass filler; a broken or rattling liner significantly reduces collector value.
• Completeness of the unit, including the original plastic cap and stopper which are often lost over time.
• Overall vibrancy of the colors, as sun-fading on the metal surface can lower the market price toward the $50 range.

How to Identify Fireball XL5 Thermos?

• Check the base for the King Seeley Thermos Co. manufacturer mark and the 1964 copyright date.
• Verify the presence of the original red or white plastic cup lid and the internal stopper.
• Look for the distinct lithographed graphics featuring Steve Zodiac and the Fireball XL5 spacecraft.
• Ensure the materials are authentic period-correct tin-plated steel with a glass vacuum insulated liner.

History of Fireball XL5 Thermos

Fireball XL5 was a popular British science fiction television series created by Gerry Anderson, known for its Supermarionation puppetry. The show, which aired from 1962 to 1963, inspired a range of merchandise, including this thermos, produced by King Seeley Thermos Company. These thermoses were commonly sold as part of a lunchbox set, a staple for schoolchildren of the era, allowing them to carry both their meal and a hot or cold drink featuring their favorite characters.
