I just found my old Duel Masters collection and I'm looking to sell it in a big bundle if possible (I don't really want to spend time selling cards one by one). I checked the average prices on the google doc you provide on the forum for these cards :
Roaring Great Horn
Evo-Crushinators of Doom
Armored Blaster Valdios
Shadowclash of Blinding Night
Stomp-A-Trons of Invincible Wrath
Lava Walker Executo
Valiant Warrior Exorious
Laveil, Seeker of Catastrophe
Schockwaves of the Shattered Rainbow
Note that all the cards are in FRENCH (except Core Crash Lizard who's in english) and their conditions are Mint or Near Mint.
Here's a picture of the collection :
From what I checked, the average global price should be 214€, but I am willing to sell the whole bundle at 150€.
Don't hesitate to DM me if you want more details or specific pictures of specific cards, I know it can be important.
Have a nice day folks!
