Steam trading cards are virtual collectibles that drop while you play. Collect a full set, craft it into a badge, and you gain profile XP.
That's the whole system in three sentences. Everything below is the detail that actually affects what you do with them — and if your goal is levels specifically, the complete guide to levelling up on Steam is the place to start.
What are Steam trading cards?
Trading cards are tradeable items that drop as you play games with card support. Each game has its own set — typically 6 to 9 cards. Completing a set lets you craft a badge, which grants 100 XP toward your Steam level plus a random emoticon and profile background.
How card drops work
Play a game that supports cards and you'll receive drops automatically, based on playtime.
The important limit: Steam only drops you about half of each set. A game with 8 cards will drop roughly 4. The rest have to come from somewhere else — trading with other players, buying on the Steam Community Market, or opening booster packs.
This is deliberate. The half-set rule is what creates the trading economy in the first place: everyone ends up holding duplicates of some cards and gaps in others, so people trade.
Once your drops for a game are exhausted, that's it. More playtime doesn't produce more cards.
Booster packs
After your drops run out, you can still receive booster packs — a random chance granted to players who own the game, weighted by how many cards exist in circulation. A pack contains 3 cards.
You can also buy booster packs with gems, which is the other half of the loop.
Gems
Gems are Steam's crafting currency. You get them by turning unwanted items — spare cards, backgrounds, emoticons — into gems via the "Turn into Gems" option in your inventory.
Gems buy booster packs. Booster packs contain cards. It's a way to convert junk into potentially useful cards, though the exchange rate is rarely generous. Gems are also a payment method some sellers accept, including us.
Sets, badges and XP
A set is every distinct card for one game. Duplicates don't count — you need one of each.
Complete a set and Steam offers a Craft Badge button on your profile's Badges page. Crafting:
- Consumes the cards permanently
- Grants 100 XP toward your Steam level
- Grants a random emoticon and random background for that game
- Gives a chance at a discount coupon for another game
A normal badge can be crafted five times — five separate complete sets — after which that game stops giving XP. The full crafting walkthrough covers the mechanics and the common failure modes.
Foil cards
Foils are the rare variant. They drop at a much lower rate and form a separate set from normal cards.
Key differences:
- A foil badge crafts once, not five times
- It grants the same 100 XP
- Foil sets sell for far more — often 10× a normal set or beyond
That combination makes foils excellent to sell and poor to level with. Same XP, much higher cost. If foils drop for you, the sensible move is usually to sell them and buy several normal sets with the proceeds.
What cards are actually worth
Across 13,704 games in publicly aggregated Steam Market data (snapshot: 25 July 2026):
| Measure | Set price |
|---|---|
| Cheapest set | $0.23 |
| 25th percentile | $0.54 |
| Median set | $0.73 |
| 75th percentile | $1.29 |
| 90th percentile | $2.27 |
| Most expensive set | $7,643.96 |
Half of all card sets cost under $0.73. Individual cards are usually a few cents.
The expensive tail is small but dramatic — sets from delisted games, or games with tiny player counts and therefore almost no cards in circulation, can reach hundreds or thousands of dollars. Those are collector items, not leveling material.
Selling cards: mind the fee
You can list cards on the Steam Community Market at any time. Two things to know:
- The Market takes a cut — roughly 15% between Valve's fee and the game's fee. The price a buyer pays is not the amount you receive.
- Proceeds are Steam Wallet funds. You can spend them on Steam. You cannot withdraw them as cash.
That second point catches people out constantly. Selling a big card inventory doesn't produce money; it produces store credit.
How this connects to leveling
Every 100 XP is one badge craft, which is one complete set. So the entire leveling economy reduces to a single question: how cheaply can you assemble complete sets?
- How many sets each level needs — level 100 is 550 sets
- What it costs to do yourself vs buy — about $202 of cards, or roughly 3,300 separate purchases
- What levels actually unlock — friend slots, showcases, badge cosmetics
Cards are cheap. Assembling hundreds of complete sets is the work.

Frequently asked questions
How do you get Steam trading cards?
They drop automatically while you play games that support them, up to about half a set per game. The remaining cards must come from trading with other players, buying on the Steam Community Market, or opening booster packs.
Why do I only get half a set of cards?
Steam caps drops at roughly half of each game's set by design, which forces trading between players. The other half comes from the Market, trades, or booster packs bought with gems.
Are foil cards worth more?
Yes, usually far more — often ten times a normal set or higher, because they drop much more rarely. A foil badge grants the same 100 XP but crafts only once, so foils are generally better sold than crafted for levels.
Can you make real money selling Steam cards?
No. Steam Market proceeds arrive as Steam Wallet funds that can only be spent on Steam, and the Market takes roughly 15% in fees. Selling cards produces store credit, not withdrawable cash.
