Question 1

How is the Grass Energy #104 Professor Program price determined?

Accepted Answer

Every price you see in PokeValue comes from live listings on CardMarket — the largest trading-card marketplace in Europe. For Grass Energy #104 we pull all the currently active listings and break them down by condition, so you get a separate price for each of the seven grades: Poor, Played, Light Played, Good, Excellent, Near Mint and Mint. Listings are filtered to English copies only and to the exact variant — regular cards never include reverse-holo or 1st-edition listings, and vice versa. Prices refresh regularly, so the values you see reflect the current European market.

Question 2

What is Grass Energy #104 Professor Program worth right now?

Accepted Answer

The PokeValue market price for Grass Energy #104 from Professor Program is around €11.64 in Good condition. The trend price is €44.13. The value moves with condition — a Near Mint copy is worth significantly more than a Played or Poor one. See the per-condition price breakdown above for exact figures.

Question 3

Why does the price of Grass Energy #104 Professor Program vary so much by condition?

Accepted Answer

Condition is the single biggest driver of value on a Pokémon card. Edge whitening, surface scratches, bends and centering issues each step the price down. A Near Mint Grass Energy Professor Program can be worth 2–3× a Good copy, and a graded PSA 10 can be worth several times an ungraded Near Mint. PokeValue prices each condition separately so you know exactly what your copy is worth.

Question 4

Where can I buy Grass Energy #104 Professor Program?

Accepted Answer

Most Grass Energy #104 Professor Program listings live on CardMarket, where European sellers post copies by condition and variant. You can also find occasional copies on Tradera, eBay and dedicated card shops. Use PokeValue to check the current market price before you buy so you don't overpay.
