This PSA10 Rayquaza GX from the "Sky's Ruler" series is a significant addition for any serious Pokémon card collector, particularly given Rayquaza's iconic status in the franchise since its introduction in Pokémon Emerald in 2002.

Manufactured by a reputable company known for its quality, this Gem Mint example reflects not only the character's popularity but also the high demand for well-preserved cards from early Japanese releases that frequently command premium prices in the collector market.

While the condition note suggests it may have been handled by an amateur, the PSA10 grade indicates a remarkable standard that still holds considerable value, especially within Japan's vibrant trading card community where authentic, high-quality pieces are highly sought after.
