These cards were distributed primarily to Latin America and those areas in the U.S. with a large Hispanic population So they may not be that easy to find.
I found my unopened pack at a local yard sale for about $.25. I think at some point I may bust this and show it off on here as there is a Griffey card I need in the 150 card base set and some among the insert sets. So stay tuned for that.
In comments below, let me know if you have busted any or picked up any singles of any.
