Reading a card
Four things on a card tell you how rare it is. Everything else — the value — builds on top of these.
- Set symbol (bottom, a little logo) — which set it's from. Older WOTC sets from 1999–2000 have no symbol at all.
- Collector number like 4/102 — card 4 of a 102-card set. A number higher than the set size (e.g. 103/102) is a "secret" card.
- Rarity symbol next to the number: ● common, ◆ uncommon, ★ rare. Modern sets add lots more marks on top of the star.
- Copyright year + artist (tiny, bottom) — dates the print and names the illustrator. Some artists (Arita, Mitsumoto) carry a premium of their own.
The rarity ladder
Bottom to top. The printed symbol and the exact odds have shifted a lot over 25+ years and vary by set — treat the odds as rough "one in about N packs."
Old-card stamps that matter
Where rarity meets money
Once you know a card's rarity, these are the levers that turn "rare" into a price:

Desirability score
Value isn't one thing — it's several multiplying together. Slide each factor and watch them compound.
What this is teaching
A PSA 10 Base Set Charizard and a PSA 10 of a random common share the same grade, but one is worth a house payment and the other a coffee. The difference is every other factor — the Pokémon, the era, how few survived — multiplying on top. Rarity gets you in the door; it rarely finishes the job alone.
Cards that are expensive for only one reason (just playable, just new) tend to fall. Cards that are expensive for many reasons at once (iconic + old + graded + scarce) tend to hold.
What grading does
A grading company (PSA, BGS, CGC) seals a card in a plastic "slab" with a number from 1 to 10. It's judging four things:
PSA 10 = "Gem Mint". PSA 9 = "Mint" (one tiny flaw). BGS adds half-steps and a "black label" 10 (all four sub-scores are a 10). A grade is also a tamper-proof guarantee it's genuine — which matters more every year.
Grade impact
Pick roughly what a raw near-mint copy is worth, and see how the grade multiplies it. These multipliers are very rough and swing hugely by card — a low-population vintage card can jump far more at PSA 10.
Is it worth grading?
Grading costs money (roughly $15–$25 a card at the cheap tiers, much more for fast service or high-value cards) and takes weeks. And the card might come back a 7, not a 10.
