The top left of the last post are the Shonen Jump Tournament cards, the most expensive would be SJC-EN001-Cyber-Stein, valued around $2000-$6000, theres one on eBay for sale in BGS 10
It also generates consistent value by drawing a card every turn or forcing difficult decisions in combat
If your cards have been in a binder for years, handled without sleeves, or moved around a lot, the condition will have a big impact on the price
While the sky-high market price is accurate as to what you may pay for an NM copy, a damaged card sold for $869.76, while one in MP condition sold for $1,250 leaving the market price's estimation as a fair value for Rayquaza.
