Flip a thrifted pair of jeans over and look at the right back pocket before you look at anything else. If the Levis red tab reads LEVI'S in all capitals, Levi Strauss & Co. says those jeans were made before 1971, and that single letter is the gap between ordinary rack denim and a pair worth real money.
Big E pairs are the vintage Levis resellers chase hardest. Recent eBay data puts the median Big E 501 sale at $145, against $62 for a regular Made in USA 501, and a clean 1960s pair sold for $2,040 through an Alaska auction house. The tab won't prove anything on its own, though, so here's how to read it alongside the rest of the jean.
What the Levis red tab is really telling you
The tab sits in the seam of the right back pocket, and Levi's own guide to spotting vintage pairs treats it as the first clue. An all-caps tab, nicknamed the Big E, means pre-1971. A tab that spells Levi's with a lowercase e came after, and that version is still sewn on today.
Big E versus small e
Not every dating guide agrees on where the line falls. One well-known denim blog argues capital E tabs point to jeans from before 1955, while Levi's and most dealers use 1971 as the cutoff. Treat the tab as your opening clue and confirm it with the inside details below.
- •Capital E on a red tab: made before 1971, per Levi's
- •Lowercase e on a red tab: 1971 or later, still in use today
- •Orange tab: late 1960s to late 1990s, small e lettering
- •No tab at all: check the inside labels before you guess
One capital letter on a strip of red fabric smaller than your thumbnail is the biggest single price signal on a pair of old Levi's.
How to identify vintage Levis beyond the tab
Tabs get cut off, fade out or get swapped, so you want a second and third opinion from the jean itself. Luckily the inside of a pair keeps better records than the outside, and checking takes about a minute.
Reading the vintage Levis tag inside the waistband
Levi's says care tags weren't added until the 1970s, so a pair with no care tag at all leans older. Thrifted's tag-by-era guide adds that paper care tags ran from the 70s to the mid 80s, while fabric labels carrying an RN number showed up in the late 80s. A three-digit number stamped behind the care tag is a factory code, which narrows things down further.
The inseam and the back patch
Almost every pair made before the mid 1980s has a single felled inseam, meaning one line of stitching runs down the inner thigh. Up on the back waistband, a thick leather patch generally means an older pair, while the papery card patch was common through the 70s and 80s.
| Detail | Likely era | What it means |
|---|---|---|
| Capital E red tab | Before 1971 | Strongest single sign of an older pair |
| Orange tab | Late 1960s to 1990s | Small e lettering on the tab |
| No care tag | Before the 1970s | Backs up a capital E tab |
| Paper care tag | 1970s to mid 1980s | Common on 70s and early 80s pairs |
| Single felled inseam | Before mid 1980s | One stitch line down the inner thigh |
| Fabric RN label | Late 1980s on | Later pair, price it as modern vintage |
| Overseas made | 2000s onward | Most production had left the US |
What the vintage Levis button stamp means
Turn the top button over and you'll often find a number stamped on the back. Collectors read it as a factory code, and 555 is widely tied to the Valencia Street plant in San Francisco, which closed around 2001 or 2002. Lists for the other numbers come mostly from forums, so never pay up on a button stamp alone.
- •No care tag at all points to a pair made before the 1970s
- •A paper care tag suggests 1970s to mid 1980s production
- •A single stitch line down the inner thigh means pre mid 1980s
- •A thick leather back patch usually beats a card patch for age
- •A three-digit code behind the care tag names the factory
Why some Big E Levis are brand new reproductions
Levi's still sews Big E tabs. Its Levi's Vintage Clothing line reproduces historic 501s right down to the capital E, and denim dealers point out that those reissues and outright fakes can carry both a Big E and a care tag. A genuine pre-1971 pair shouldn't have that combination.
Reissues aren't worthless, but you price them as current jeans, not as 1960s denim. If the tab and patch look crisp on otherwise tired denim, slow down and read every label before you pay.
A capital E next to a modern care label is a mismatch. True pre-1971 pairs left the factory without care tags, so that combo usually means a reissue or a fake.
- •Big E tab paired with a printed fabric care label
- •Bright, crisp tab and patch on heavily faded denim
- •Overseas made label on a pair sold as 1960s denim
- •Double stitched inseam on a pair listed as pre 1980s
What vintage Levi 501s actually sell for
This is where the tab pays you. Across 41 recent eBay sales tracked by one valuation site, Big E 501s sold for a median of $145, with the middle half landing between $33 and $400 and the best example reaching $2,500. The same site's data for ordinary Made in USA 501s shows a median of $62 and a tight $50 to $70 range.
| Pair type | Median sold | Typical range |
|---|---|---|
| Big E 501 | $145 | $33 to $400 across 41 eBay sales |
| Made in USA 501 | $62 | $50 to $70 across 41 eBay sales |
| Top Big E sale | $2,500 | Exceptional examples only |
| 1960s Big E at auction | $2,040 | Selvedge, dark wash, single sale |
The spread on Big E pairs is huge because condition and size do most of the work. That $2,040 auction pair had a clean dark wash, selvedge denim, copper rivets and its original tags, and it hadn't been distressed. A blown-out crotch or a chopped hem drags a Big E toward the bottom of the range fast.
Levi's 501 vintage maths after fees
A $145 sale isn't $145 in your pocket. Marketplace fees and shipping come off the top, which we broke down in our look at how eBay fees cut into thrift flips. Even so, a confirmed Big E pair is one of the few denim finds where the profit can run into the hundreds.
Most Made in USA 501s cluster between $50 and $70. Big E pairs start in the same neighborhood but have a ceiling more than thirty times higher.
A quick checklist before you buy a Levi second hand
Racks move fast, so run the checks in the order that rules pairs out quickest. It's the same habit that works for dating old Nike sweatshirts by the tag and for single stitch band tees: read the labels before you fall for the wash.
- •Right back pocket: capital E, lowercase e, orange tab or none
- •Inside waistband: no care tag, paper tag or fabric RN label
- •Inner thigh: one stitch line or two
- •Top button back: note any three-digit factory stamp
- •Damage: check the crotch, hems and pocket bags for holes
If a pair passes the first three checks, it earns a spot in your cart before you know the exact year.

Questions people ask about vintage Levi Strauss denim
How to tell if Levis are vintage when the tab is missing?
Go straight to the inside. No care tag, a single felled inseam and a leather back patch together point to an older pair, and the three-digit code behind the care tag can narrow down the factory. Without a tab you'll price lower, but the jeans can still sell as Made in USA vintage.
Are small e Levi's worth anything?
Yes, just less. Lowercase e tabs run from 1971 to today, so the value comes from the other details. A Made in USA 501 with the right inside labels still sits in that $50 to $70 band on eBay.
Do vintage Levis jeans need to be 501s to sell?
No, but 501s have the deepest sold history, which makes them the easiest to price. For other models, check sold comps for that exact lot number and size before you list.
