They are the most expensive of the original series/card.
Three titles: Scoot, Garbage Can-dy, and Jungle are common and can be bought for ~$10-15. (Double prints)
Scoot that does not have its copyright, though, is worth ~$125+ likely.
I put all other titles at $50 on my price guide I believe, but it seems as though the market is up a bit, so take that with a grain of salt.
It is worth mentioning that some titles might be more desired and/or less seen on the market, driving up their value. Or, some may need a more seen card for the last in their set and will pay more for it.
Some titles that I think are a bit more uncommon and might sell for a bit more as a result are:
Old Grandmom
Fling Ems
Gillo Port
Sufferin
But, when I say these seem more uncommon, it doesn't mean they were printed less than any other of the non double print stickers. They just show up on the market less.
The entire set would likely sell for $1500-2000 depending on condition.
The puzzle can also sell for $400 on a good day, but not completely sure for average value.
To expand upon the puzzle, the right side always garners more value. The TR is always the most valuable piece. It can sell for ~$100+ alone.
Need any more info? Feel free to ask me or anyone else. (There's some on here who probably know more.)
