Hello there, i was wondering what your think of this,

A person message me asking about me buying a shadowless 1st edition charizard PSA 9, i asked about pricing ect and weather he would accept part trade, he said maybe for high end stuff.
i said i have a psa 9 shadowless holo set missing gyarados hitmonchan magneton and nidoking. he doesnt mind that as his looking to buy a complete psa 9 shadowless set anyways (maybe why he is selling his charizard 1st edition’)
i was wondering what a fair trade would be

His offering a PSA 9 shadowless 1st edition charizard
I’m offering a complete shadowless PSA 9 holo set missing the gyarados hitmonchan magneton and nidoking, what do you guys think about how much money should be added? i was thinking somewhere in the region of £500 but is that too low or too high or about right? what do you guys think ?

Just from ebays sold history 1st Ed Charizard psa 9 sold in may for 5200 in auction. psa 9 shadowless holos sold for about 120-150 minus the big 3.which is about 200-300 more in a psa 9.

Charizard: $1500
Chansey: $500
Blastoise: $350
Venusaur: $250
Raichu: $250

7 other holos: $125 per so about $875?

So you have roughly $3725 here and the card you’re looking to trade for is $5500+. I’m not good with british pounds, but it’s safe to say you would need to add at least 1000. Try to see how much they’re willing to accept.
