I just dont trust the authenticator, to many have been implicated in fraud on fake grades on cards, i only trust PSA. I did google them and they came back pretty shaddy. I dont see paying $300 credits for a $40 card.
Yes, we have a couple dozen in our collection, its a great card you have, We have over 50 1989 upper deck Griffey Rookies so far, 6 just in the last 3 weeks.
