Actually, when I was little my dad was friends with the Burger King Manager... he would have a lot of left over happy meal toys and stuff...
I have and still have all the lord of the rings toys except one that i accidently broke, they formed a circle when you completed the collection! I also have all the Lord of the rings glowing cups they had... I did have a whole bunch of pokemon toys, till i gave em away... I do still have all 6 of those limited edition pokemon gold colored cards they used to give away as well...
I tried to get into collecting/selling them. Im somewhat clueless on the value on most of them. It seems that every flea market or thrift store I visit has boxes of them (mostly mid-80s to now). I know lots of old ladies who eat that stuff up. They assemble whole collections and make hundreds selling them on Ebay.
The only fast food toys I have is four of the bears from McDonalds' recent Build A Bear promotion. It's rare that they have any happy meal toys I'm interested in, but I can't resist a teddy bear. I just wish I could have gotten some different bears. I have four of the same one.
I collected fast food toys like insanity. I'm not an avid collector anymore, as I don't eat fast food anymore. But once in a while my mother will go out and get herself a burger at Mickey D's (and send her intestines to hell...ick), and get me a toy of the week for the heck of it. But only if it's Disney. I still love my Disney junk.
I mostly have McDonalds toys of the Muppets and other Jim Henson stuff. Manly because I collect Muppet/Henson stuff, here a picture of some of the stuff I have from McDonalds...
I also have but not Pictured The Red and Mokey Fraggle Rock Happy Meal boxes (Never used) The whole set of Dinosaures (including under three toy) The set of Muppet Treasure Island (including under three toy) Sam the Eagle and Miss. Piggy from Sweden Happy Meals
Oh the the ones pictured of Miss.Piggy and Fozzie are the Muppet 25 years happy meal toys from the UK. They were never here in the US.
DUDE Astroniks are awesome, on Halloween my town rocked they used to give those out with their candy and I had like 40000000000000 of them, now I have zero lol, and they are pretty tough to track down.
Right now I have only have two mcdonald's stuff: a mac attack kit (a hemp bag with certificates in there) and a boo pail (the witch, its so friggin sweet)
