I think the $10 strike you're referring to is from the Suncoast. It's been released for a bit now and seems to be readily available. It was tough to win at first but I believe they adjusted the hopper mix. I know there are/were the Suncoast Pentagon $10 strikes also being auctioned on www.jackpotauctions.com.

There is also a recent release from the Palms in LV, their $200 Pentagon strike. Those are the only two I am aware of anywhere at this venture and nothing from Gaming Commission indicates otherwise, at least as of the end of December. Hope this helps.
