Two letters is enough. A name, a set, or a collector number like 199/165.
Where a card price comes from, why the same card has two of them, and how to read a number before you believe it.
Why card prices change: reprints, rotation, tournament results, grading populations, currency, seasons and social hype, each explained with what it does to a price and how fast. Read the move before you react to it.
Is grading worth it: what PSA, Beckett and CGC do, what it costs, how much a 10 adds against a 9, and the simple calculation that tells you whether a given card should go in a holder.
Cardmarket vs TCGplayer: two markets, two currencies, two ways of computing a price. Why the figures differ by 20 to 40 percent, what each number actually measures, and which one applies to you.
How much is my Pokémon card worth: identify the exact printing, judge the condition, then read a marketplace figure with its date. The method, the traps, and the free tools.
