I just bought some puzzles and these were among them:

This is a big fat pen with a six sided slidey tile puzzle around the outside. Each layer can rotate. The label on the end says "(c) 1982 ITC Puzzle Pen Made in Hong Kong"



This is a seven sided puzzle (for the days of the week) and all layers can be turned individually. I guess that the numbers have to be arranged so that so that a monthly calendar can be read around the outside. The top has a slot in it so that it can be used as a money bank, or it can be removed and used as a pen holder. Its box just says "Made in Taiwan"

yep, i have - in the museum

They must be worth ££££££££££££

Not really, I have seen them both sell for about $20-$40 USD. I even thought that was too much at the time.

Oh well, I'll have to wait another year to become a millionaire

Honestly, I've never seen them sell for this much. They are certainly neat to have, but not worth millions.

ITC would refer to Ideal Toy Corp., the company which also held licensing rights to the Rubik's Cube in the early '80s. It was marketed as "from the makers of the Rubik's Cube" on the original packaging. I don't see them offered for sale very often. I've seen the yellow one sell for $200 in new and sealed condition a couple years back, and took the opportunity to buy both the red and yellow versions new and sealed for quite a bit less.

The calendar cube is quite neat. I also have one, though missing the top coin slot cover. You actually don't need to solve it every month - once it's solved you can just rotate all the other layers accordingly the next month. Unfortunately, this one is quite easy to find.

Link, perhaps? I'm interested in one.
