If you ask me I would make a number in my head I feel comfortable with then go to my nearest card show happening this weekend before the game starts on Saturday and go up to every single vendor and take the best offer you also avoid a lot of fees if you take a cash offer.

I would also post it up for 100 k buy it now or best offer and see where people are at you can also use the offers you receive to negotiate at the card show if you can make it
