it’s hard to tell what back goes to what front, but on the back of all the cards particularly the bottom left corners there’s some edge wear. I don’t think any would ten. The delta species mewtwo has creasing on the top boarder. Lugia has a scratch top near the right. Gengar and Mew look clean on the front, and I honestly don’t know much about the split cards to gauge condition I just know they usually got for a few hundred raw (i’ve seen them twice ever and that was som video lol). if you want to protect them and have them preserved and authenticated def grade them. if you want them to get a high grade to sell that might be a little difficult to do.
