A Detailed Guide to Dating Vintage Levi’s Jeans

Dating vintage Levi’s jeans is a fascinating journey for collectors, enthusiasts, and fashion historians alike. The humble tags and subtle details found on these iconic garments hold a wealth of information, allowing us to pinpoint their era, understand manufacturing changes, and even determine their rarity and value. Far more than just branding, Levi’s tags serve as vital chronological markers, evolving through decades to reflect technological advancements, marketing shifts, and global expansion. This detailed guide will explore the key elements of Levi’s tags and other crucial identifiers to help you accurately date your denim treasures.

The Iconic Red Tab: Big ‘E’ vs. Little ‘e’

Perhaps the most famous dating indicator is the red tab on the right back pocket. Its evolution marks one of the most significant transitions in Levi’s history:

• Big ‘E’ (Pre-1971): Jeans produced before 1971 feature a red tab with “LEVI’S” written in all capital letters, specifically with a capital ‘E’. These are highly sought after by collectors due to their age and scarcity.
• Little ‘e’ (Post-1971): From 1971 onwards, the ‘E’ in “Levi’s” became lowercase. This seemingly minor change was part of a broader rebranding effort, making “little ‘e'” tabs a definitive marker for post-1971 production.
• Variations: Early Big ‘E’ tabs sometimes feature a “V-stitch” where the stitching on the tab forms a ‘V’ shape towards the top. Other less common tabs include blank tabs (a rarity), orange tabs (used for fashion lines), and black tabs (for specific styles or washes).

The Two-Horse Patch: Material & Wording Clues

The “Two-Horse Pull” patch, traditionally found on the back waistband, also offers significant dating clues:

• Leather Patch (Early Era): Very early Levi’s (pre-1950s) often featured genuine leather patches. These are very rare to find intact.
• Paper Patch (Mid-20th Century Onwards): Paper patches became standard, depicting two horses trying to pull apart a pair of jeans, symbolizing their strength.
• “Every Garment Guaranteed” (Pre-1971): Before 1971, patches frequently included the phrase “Every Garment Guaranteed.”
• “Care Instruction Inside” / “Care Instruction On Garment” (1970s Transition): As care tags were introduced, the patch wording changed to reflect this, indicating that washing instructions could be found elsewhere on the garment.
• Factory Code & Sizing: Later patches often include the waist and inseam measurements (WXX LYY) and sometimes a factory code.

The Elusive Care Tag: The Ultimate Date Code

The care tag, introduced around 1971-1972, is arguably the most precise dating tool for post-Big ‘E’ jeans. Located inside the jeans (often sewn into a side seam or under the waistband), it provides crucial information:

• Early Paper Tags (Early 1970s): The very first care tags were often small paper tags, sometimes with minimal information.
• Cloth Tags (Mid-1970s Onwards): Cloth care tags became standard, providing detailed washing instructions and fabric composition.
• Date Code: Most importantly, these tags often contain a hidden date code. This is usually a three or four-digit number, often positioned at the bottom right. For example, ‘0217’ might indicate February 2017, or ‘217’ indicating the 2nd week of 1977. The format can vary, but the last two digits often represent the year, and the preceding digits the month or week. Matching the factory code (e.g., ‘555’ for Valencia Street) on the care tag to the button stamp significantly enhances dating accuracy.
• Made in USA: The presence and location of “Made in USA” can also provide clues, as Levi’s production eventually expanded globally.

Button Stamping & Rivets

• Button Stamping: The number stamped on the back of the top button (e.g., ‘2’, ‘6’, ‘555’) is a factory code. For vintage jeans, especially Big ‘E’ era, these codes can be matched to known factory lists to narrow down production dates. Post-1970s, this number should ideally match a code found on the care tag.
• Rivets: Early rivets were plain. Later, “L.S. & Co. S.F.” (Levi Strauss & Co. San Francisco) was embossed on the front of the copper rivets. The presence of hidden rivets on the back pockets (covered by denim) is a strong indicator of pre-1966 production.

Selvedge & Stitching Details

• Selvedge Denim: Selvedge (or selvage) refers to the finished edge of denim fabric, often identified by a colored line (most famously red, hence “redline selvedge”) along the outseam when the cuff is rolled up. Redline selvedge was standard for Levi’s 501s up until the early-to-mid 1980s, when mass production led to the widespread use of non-selvedge denim.
• Stitching: The color of the stitching (e.g., lemon yellow, orange, or mixed) and the style of the arcuate (the double arch stitching) on the back pockets can also provide dating clues. Early arcuates were often single-needle stitched, becoming double-needle stitched later.

Zippers & Other Hardware

For zippered Levi’s models (e.g., 505, 502), the brand of the zipper can be a helpful indicator:

• Talon 42: A common zipper found in Levi’s from the 1960s and 1970s.
• Scovill, Gripper, YKK: Other zipper brands were used, and their specific designs can help narrow down the era.
