Here's the back of the Rose card. (The Grote isn't mine, so I have no access to it. In fact, it seems to have disappeared from ebay, but I can't find it in the sold/completed auctions section. A private sale? If so, some seller did quite well for himself.)
PSA standards for centering on a 9 are "90/10 or better on the reverse," so this card fits those parameters.
