well as 10’s and if you find the right buyer they will easily be $100 each (CoroCoro Mew and Charizard even more)! So all together would be $1000+ I’m not sure if someone is willing to spend such great amount at once so I would suggest selling them seperately. But you can really only tell when you know your grades. I hope you get some sweet gradings!
I used to own that set plus the other 2 Neo 3 shining cards he has for sale. I think I sold all 10 to him for about £550 iirc so that should give you an indicator of what the set should sell for.
If you’re Japanese Shining Charizard got a Gem Mint 10 it would be the first. I’d say that is something to shoot for right there ;)Charizard collectors would go nuts to have it!
Speaking as someone looking for shining cards to complete my Neo sets, I’d list them individually. I cannot see myself parting with a grand to buy them all together even if I had the money. Plus, you could probably get away with charging slightly more for the individual cards than as a lot.
Once you crack open a PSA case and resubmit the card for grading, there is no guarantee it will get the same grade as before. If resubmitted it would likely get a PSA 9 but it is not a definite.
