WTT/ 1st Edition Venusaur base set

Trading my Psa Mint 9 1st edition shadowless venusaur
For Psa 10 charizard unlimited base set holo

You should throw something else in because they are not close to the same value, around 150-200USD difference, of what I have seen lately on eBay.

-Venusaur psa 9 1st edition shadowless sold for 625USD on Feb 24th on eBay.
-Charizard psa10 Unlimited sold for 860USD on April 2nd on eBay.

Charizard psa 10 on eBay sold listings
$614- march 27th
$616- February 27th
I guess with the one that sold for $860 the fair market value would be just under $700 therefore if someone was truly interested I may add $50-$75
