Eventually I acquired nine of the ten cards. Having the Top NINE Moments is not acceptable. I don't like holes in my collection, and I've been searching in vain for the missing tenth, the Ryne Sandberg game card. For six months, my search has come up empty. I decided I would have to take a different route...instead of looking for the single card, why not look for the entire set.
And then it was easy. A couple sets popped up at a fairly reasonable prices, and the hole is now filled.
