There are some major casino in the wilds of Minnesota, but many are spread out in the remote areas. One on the less remote (and biggest) is the Grand Casino Hinkley, on the Interstate between the Twin Cities and Duluth. Now when I hit a casino to harvest cards I try to check the top of every machine and it took over an hour to go through this place. And they have a big variety of cards to report on. The Hinkley cards are basicly silver, with the only variation on the front being the "large GRAND" on type 1 and "small GRAND" on types 2 and on. On my trip last weekend, I found a mystery card, white with only a mag strip on the back and a little imprinting on the front. But I have a suspicion... the card desk had mention of a gold card for high rollers, but I didn't find or even see one. But I got a couple of these white cards, and saw more of them in play -- especially in the high roller area. The date on the card below was the day I was there. Since they obviously were not out of the silver cards, this might have been a temporary replacement for the gold cards that were out? Could be.
