Near mint Mega Charizard X ex sells for ~$750
Raw, near mint copies of this card were selling prior to Phantasmal Flames release on November 14th at a peak of around ~$2.2k. Since release, prices have come down significantly and continue to come down. It is currently the most graded copy of the set with a total of 281 and 186 in a PSA 10. With restocks of sealed products coming to various retailers early next year this could help drive the price down further before it climbs up again.
