I feel your pain dude. 100X definitely left a bad taste in everyone's mouth. It's very likely those tickets were destroyed or thrown in the trash. If I remember, the last Grand Prize claimed was around 609K and the print went up to the 630's, but it wansn't clear to tell if there was an actual prize left or not or if the missing prizes were from earlier in the rolls.
I have an idea. We're told the Scratch Producer has a master key of the winners, but not where they're shipped to, and the Lottery has a master key of all the rolls and where they go, but no knowledge of the winners.
So here's a suggestion. At the end of a scratch game after prizes can't be claimed anymore, both the Scratch Producer and the Lottery should provide their "Master Key" for the scratch game so that all tickets can be accounted for and it can be determined where those rolls went, whether they were sold/destroyed, etc. That way we could get an idea if it's still out there.
As for 2MJ, there may be some hope the last $2M is still out there. It would naturally appear in the 250K-277K range based on the roll numbers of the previous 5 winners, and there's plenty of rolls out there in the remaining supply. Then again there should have been a claimed jackpot in the back of the roll on $200MS but it never appeared, so who knows?
