When in comes to collecting anything, the prices are most influenced by supply and demand. LOTRTCG is a dead game, and I doubt he'd think anyone actually would pay over $100 bucks for little scraps of colored cardboard that he's had for several years. The trick is to pretend you read the books but have never heard of the game and offer $10, then let him drive it up as much as he dares. He probably just wants to get them off of his hands, and he won't try and overcharge you for them for fear that you might back down. However, you probably gave away the game by going "ZOMG, LOTRTCG! How much do want for them? I got Benjamin Franklin's in my wallet!"
