I just bought a huge collection that had a TON of 2006 Allen & Ginter Mini cards in it. It doesn't appear searched at all as there are bunch of the hard to find SP's in the lot as well. There are also HOF and superstars. There are of course commons too. If you have EVER though about building this set, this lot is a great deal. I'm not much of a set builder of else I might just go for it. Most are the regular backs but there are also some of the A&G backs, which are more rare.

I haven't looked up every single card, I'd say the lot books at least $300-$350
I'll throw in some other years of A&G mini's too. About 250 cards in all -- for $30 dlvd.
