I agree, but some of his other prices are high (Nitschke mini helmet for $700). I don't immediately seee any blatant red flags, though my knowledge outside of Packers stuff is a bit limited . . .
He does post SOME good pieces. Couple weeks ago a Jeter ball sold $210 which usually is fixed at 275-500 easily. CC sabathia ball at 75 bucks isn't too bad as well. You should keep checking him sometimes i find some nicely priced things that i wouldn't complain to pay for at all
