My kids are my caching partners, and generally they will pass on McToys unless of course it follows a certain theme, we once traded for a Happy Feet toy because one of them collects penguins. For the most part the kids look at all of the contents and say some are cute little things, or look at that, but generally there hasn't been a lot that's really been a must have. They are more into caching for the hunt, which is great! If there's something they want it's just an added bonus for them. As for foreign coins, they'd probably love that.
