Good point. Just a comparison of charizards, dark zard came before blaines zard. But because there’s 333 1st edition psa 10 copies of dark zard as opposed to 231 1st edition psa 10 cards or blaines zard, that might also be why.
The team rocket set has always been my favorite. I love the dark pokemon and their art. I love the box and pack arts. I agree with you that it is insanely undervalued and sitting right next to the gym sets and neo discovery in underappreciated wotc sets. However, I decided to check booster box prices and surprisingly 1st ed TR boxes are regularly selling around the $1,900 mark while 1st ed fossil is only sitting around $1,600. Jungle pushing over 2k. Not sure why those prices are what they are but I definitely found it interesting.
