We have a new collection going in our house at the moment.  They are Squinkies.  Little rubber animals, people, things that come in little clear balls.  Emma just loves them.  She has 19 already (although that is not hard because they come in packs of 16).  I wonder if it will be something she will continue to collect or forget about?  Emma has never really stuck to any collections she has started.  She is enjoying them at the moment though and plays with them a lot. What do your kids collect?  Nathan collects rocks and Pokemon cards.  He really loves his rock collection and is always on the lookout for new and interesting rocks to add to it.
