The Giratina V SA is currently sold for around 100,000 JPY (~US$674), and other high-value cards like a PSA 10 Umbreon VMAX SA are sold for around 400,000 JPY (~US$2,697)

If you ever have a chance to buy one, ensure you double-check whether it's a regular holo or reverse holo, as this changes the value even further
