Jon CanfieldLeon was dead on with his description except for two small points.
I don't believe that either the Hassan or Mecca packs had tin foil with them. With Hassan, I'm positive. A number of years ago, I had the pleasure of watching one being opened with a NM triple folder pulled from the inside (albeit it was badly micut top to bottom). The card was folded and inserted right behind the cigarettes with the back of the inner panel in direct contact with the cigarettes. Also, of note, the inner slide of the Hassan pack had a baseball scorecard printed on it. I don't know if all Hassan's that held cards had a baseball scorecard printed on the inner slide but this one did. I purchased the pack after it was opened and can provide scans later tonight if you would like.
Now, in terms of value, I disagree slightly. If you have the correct period pack, I think the values would be closer to $50 each or so, maybe even more on an eBay auction and who is bidding. The packs are certainly not the most rare, but since there are many double/triple folder collectors out there, these make great companion pieces.
