PSA cards?

Hey,
Just got a few cards back from PSA and im looking at buy a couple others, what would you pay/say these are worth?

PSA 10 umbreon holo from neo discovery 1st ed
PSA 10 web charizard unlimited
PSA 9 Web charizard 1st ed
PSA 10 VS umbreon
PSA 10 Pikachu lvl x

I had a quick look for them but couldn’t find any listings (apart from a $700 for a psa 10 zard)

Cheers
