COS Sunglasses Resale Value

COS sunglasses: price by condition

Seller-declared grades, sterling with an approximate US dollar equivalent at £1 ≈ $1.33 (July 2026). What each grade means.

What holds its value across COS

• Oversized wool and wool-blend coats, which are the label’s signature and the thing buyers search it for by name
• Archive and limited-edition pieces, which are produced in small runs and are the only part of the range with a collectors’ element
• Plain, structured tailoring in neutral colours, which dates far more slowly than anything printed and stays saleable for years
• Heavier knitwear in merino and wool blends, which holds its shape where the cheaper high-street equivalents do not

What pulls COS resale value down

• Pilled knitwear, which is the commonest fault and shows immediately against the plain colours the label favours
• Faded blacks and washed-out greys, which are most of the range and where fading is most obvious
• Anything with a broken or replaced signature button or fastening, since the hardware is deliberately minimal and any substitute shows
• Basic jersey pieces, which are cheap enough new that a used one rarely justifies the postage on its own

Identifying and dating yours

1. The neck label reads COS rather than any sub-line, and the care label carries a product code buyers can search to confirm the season
2. COS sizing runs large and is cut deliberately oversized, so give flat measurements — buyers who have not worn the label before consistently order wrong
3. Photograph the shoulder seams and the inside of the coat, because the construction is most of why somebody chooses this label secondhand

What lifts any sunglasses, whatever the label

Designer frames hold value reasonably, but the market is full of counterfeits, so anything that proves authenticity is worth including.

• Recognised designer and optical brands
• Original case, cloth and papers
• Lenses free of scratches and delamination
• Model and serial markings legible on the arm

And what pulls one down

• Scratched lenses, which are costly to replace
• Loose hinges and stretched arms
• Missing case and documentation
• Counterfeits, which buyers check markings for

Working out what yours is worth

1. Find the model and serial markings on the inside of the arm
2. Hold the lenses to the light at an angle to reveal scratches
3. Gather the case, cloth and any paperwork

What to state in the listing

• Brand, model number and colour code from the arm
• Lens width, bridge and arm length, printed on the inside of the arm
• Lens condition, including any scratches or coating wear
• Whether the case, cleaning cloth and paperwork are included

Brand, model number and colour: “Ray-Ban RB2140 Wayfarer, Tortoise, 50mm”. The model number is exactly how buyers search designer eyewear, and the lens width matters for fit. Say whether the original case is included, because on designer frames it adds real value.

Preparing and photographing it

1. Clean the lenses properly and inspect them at an angle for scratches, which are almost invisible head on.
2. Find the model number, colour code and lens width printed on the inside of the arm, and photograph it.
3. Check the hinges for looseness and confirm the nose pads and screws are all present.

1. The frames front on, folded, on a plain background
2. The inside of the arm showing the model number and sizing
3. The lenses at an angle in strong light, revealing any scratches
4. The case, cloth and any papers included

When it sells best, and handing it over

Strongly seasonal, peaking April to August. Designer frames sell year round; high-street sunglasses barely sell outside the summer.

Small and easy to post, but fragile without a case. If you do not have the original, use a hard box rather than a padded envelope.

What buyers ask

Does COS clothing hold its value?

Reasonably, and better than most of the high street, because the designs are plain enough not to date. Coats and tailoring do best; plain jersey basics are barely worth listing on their own.

What size should I list a COS coat as?

Give the label size and the flat measurements together. COS is cut oversized and the label size alone misleads more buyers on this brand than on almost any other.

How much are COS sunglasses worth?

Roughly £10 to £120 depending on condition, against £10 to £120 for sunglasses generally. The identification points above are what move a listing to the top of that range.

What the fees would take elsewhere

At the mid-range £65 for COS sunglasses, against what the commission marketplaces would deduct:

Seller-side rates verified 26 Jul 2026, percentages only — the per-order and processing charges those platforms add are excluded, so the real gap is wider.
