What About Cheerios Pennies?

I recently wrote about the Cheerios Dollars, which are the Sacagawea Dollars that were put into 5,500 lucky boxes of Cheerios cereal back in early 2000. These coins are fascinating because they were struck from a different set of dies than normal Sacagawea Dollars were struck from, and they're currently worth as much as $10k each because very few of them have come onto the market.
I should have foreseen the email avalanche I was about to be buried under! Although almost nobody can turn up a Cheerios Dollar these days, there are 10,000,000 Cheerios Pennies out there, and I feel like I've heard from fully half their owners! Most of them want to know how to get the $10,000 their coin is worth. I've had to break the bad news to these folks, that only the Cheerios Dollar coin is valuable. As for the Cheerios Penny? Well, it's not so bad that they might as well just go spend it, but as long they keep it on that little card, it's worth a few bucks on eBay. Then again, if they keep it on the little card, it'll probably get PVC damage from the plastic sealing it in. (Or are these cards made from archival-quality packaging by some chance? Does anybody know?)
I actually had a bear of a time finding a decent-quality photo of the Cheerios Penny on its little card. I finally tracked one down on an interesting site called X-Entertainment.com. The site is run by a fellow who collects (among other things) the junk that manufacturers put into cereal boxes for the kids to find. He has a page about the Millenios special edition collectible box on which he states that the Cheerios Penny and Dollar coin premiums were actually placed into five different kinds of cereal! Can anybody confirm this detail, and tell us which five cereals were included in the promotion?
Update: Reader Fred says (in the Comments below) that there were five different flavors of Cheerios, and that the coins were found in boxes of them all. The flavors included Honey Nut Cheerios, Team Cheerios, and maybe Frosted Cheerios. Fred also tells us that he used a metal detector on the boxes of cereal at the stores to tell which boxes might have the larger (dollar) coins in them! How devilishly clever! Thank you for sharing, Fred! :)
