The Orange "Hot Slots" (plastic temp card-similar to the paper card) was the 7th issued. Page 34 of the "guide". Value in the 4th edition is- 3. Hope this helps. We are working on the 5th edition, and so far this year have added over 1,000 new cards. I'd like to have it in print by the 1st of the new year. Keep your fingers crossed. Patty Lamb
