Each shows expected net = graded value − raw ($13) − fee. PSA 10 ≈ $92 (est). Best case (top grade via PSA): +$34.

PSA usually resells highest for Pokémon; BGS & CGC grade a bit cheaper but sell for less. Assumes a clean near-mint raw (~20% top grade / 42% one below). A guide, not a guarantee — centering & condition decide the real grade.
