Every CS2 skin has a rarity grade, shown by a color from white to red and gold. It is natural to read that ladder as a measure of how hard an upgrade will be. On a skin upgrader, though, the grade is not what sets the distance to a target. Market value does, and the two can point in opposite directions.
What the Rarity Grade Measures
Rarity is a fixed property of the skin, and in case drops it decides which probability band an item belongs to.
The Grades and Case Odds
From most common to rarest, weapon skins run Consumer Grade (white), Industrial Grade (light blue), Mil-Spec (blue), Restricted (purple), Classified (pink), and Covert (red). Knives and gloves sit above Covert and are shown in gold.
The odds Valve disclosed in 2017 for standard weapon cases are 79.92% Mil-Spec, 15.98% Restricted, 3.20% Classified, 0.64% Covert, and 0.26% for gold items. Not every case follows this table. The Genesis Terminal has its own published split with no gold tier.
Why Grade and Price Come Apart
A skin’s grade sets its place in the drop system, not what people will pay for it.
Cases Where the Order Inverts
Design popularity, wear, pattern, and demand move price independently of grade. A desirable lower-grade skin with a scarce float, pattern, or limited supply can be worth more than a less sought-after skin from a higher tier.
A same-weapon, same-wear pair shows the gap. On SteamAnalyst’s aggregate prices around September 30, 2026, a Field-Tested AK-47 | Aphrodite, a Covert skin, was about $14.69, while a Field-Tested AK-47 | Redline, a Classified skin, was about $28.16. The Aphrodite is a Limited Edition Item released in January 2026, not a case skin, so the pair illustrates price rather than case odds.
Valve’s October 22, 2025 update let players exchange five Covert items for a knife or a pair of gloves. Press coverage afterward reported sharp rises in Covert prices, though those reports are anecdotal.
Where Rarity Does Set the Odds
Rarity is the rule that governs official trade-up contracts.
How Trade-Up Contracts Use Grade
Per Steam Support’s wording, a standard contract takes 10 skins of the same rarity and returns one skin of the next tier up, from a collection of one of the items you put in. Each input adds equal weight to its collection, so seven skins from one collection and three from another give a 70% and 30% split. Grade decides what the output can be, and the mix of collections decides the odds. Price plays no part in the rules.
Where Value Sets the Odds
A third-party upgrader works on a different principle from a contract, and price is the input that matters.
How GudDrop Sets the Chance
According to GudDrop’s upgrade page, your odds depend on how far apart the value of your items is from the target’s value. Risk settings run from 30% to 80%, and only targets priced suitably for your selected items are shown. A failed attempt means the items you used are gone. It follows that a cheap Covert and a pricier Classified can sit at very different distances from the same stake, whatever their colors say.
Steam Fees and Comparing Values
If you compare a skin’s Steam value with your upgrader stake, remember that Steam’s listed price is what the buyer pays. Steam’s Community Market adds a transaction fee and a Counter-Strike game fee, so the seller receives less than the buyer pays, and Steam’s sell dialog shows the two amounts in separate boxes, “Buyer pays” and “You receive.” GudDrop states that it charges no separate fee for the upgrader, but its page does not say how it values skins, so compare against the value shown in the interface.
Using the Colors Properly
Use the grade to judge how scarce a skin is in case drops and whether a trade-up contract could produce it. Use the value shown on a skin upgrader to judge how far you are reaching. A pink skin can look like a small step and still sit far from your stake.
