Decoding the Levi's 501 "R Long Tail" Button
Levi's 501 jeans have always been defined by their details. Among the most iconic is the button fly, a feature that has remained unchanged for over a century. While most other jeans use a zipper fly, the 501's unique button closure has been a hallmark of its identity.
Over the years, Levi's has experimented with different features, but the button fly always returned. One interesting and rare detail found on some vintage Levi's 501 jeans is the "R Long Tail" button.
What Is the "R Long Tail" Button?
When you look closely at the lettering on the metal button—specifically the "LEVI STRAUSS & CO." inscription—you might notice a subtle printing error on the "R." In some cases, the vertical line of the "R" appears elongated, as if it has a "long tail." This is believed to be a minor flaw from the original manufacturing mold.
This small detail is highly sought after by collectors and helps to date the jeans.
Key Production Eras for the "R Long Tail"
The "R Long Tail" button was used on Levi's 501 jeans from approximately 1953 to 1972. This period overlaps with several significant eras of vintage Levi's production, including:
-
Red Jeans (1953-1985): These jeans are known for their red-line selvedge fabric.
-
Selvedge Fabric Jeans (1953-1976): These refer to any jeans made with selvedge denim.
-
Big E Jeans (1953-1971): This era is defined by the capitalized "E" on the red tab.
The "R Long Tail" button is a crucial detail for authentication and dating, especially if the red tab has been removed or is hard to see. If you find a pair of Levi's 501 with this button, it can confirm that the jeans are from the selvedge fabric era and were produced during the time of the "Big E" tab.
Why It's a Collector's Item
Finding a pair of Levi's 501s with the "R Long Tail" button is rare today. If you happen to find one at an affordable price, it's a worthwhile find for any enthusiast. This small detail places the jeans squarely in a valuable vintage era, making them a great piece for a collection or for everyday wear.
