I didn't even know these were made. I completely missed them when Ginter came out in August. But apparently there was another mini version in addition to the regular, AG, AG no number, and black border minis. Baseballcardpedia calls the version the A&G Bats version...
...I call it the red version. As you can see, the cards are hand-numbers to 25. With only 25 of these out there, I guess I can see how I missed them.
And with only 25 of them available, you'd think that they would go for a high price. But I suppose that with Ginter being four months old, not too many collectors are chasing these anymore because I was able to get mine for only five bucks.
I'd say it was worth the wait.
