Pin trading has been great for my DD 6. Here's some info/tips:
1. Trading is done with official Disney pins that you can buy at the parks, hotels, downtown Disney shops, and maybe the
Disney Store (although I think they've stopped, but I'm not sure).
2. Most "standard" pins cost around $6.50. Other "special" pins cost $8 and up (I've seen some for sale for over $100). Some pins you can't buy, but get only through trading with CM's or as part of certain special events.
3. CM's will always trade any Disney pin that they have for any Disney pin that you have (as opposed to park guests and professional traders who will want to trade for a "better" pin).
4. One exception to #3 is that a CM can't take a pin if they already have it (or maybe if they already have two of it). So some of the "free" pins you can get (such as with certain vacation packages) can be difficult to trade late in the day after everyone else has unloaded their's.
5. Some CM's wear a light blue lanyard that is for trading only with children (I'm not sure up to what age).
For young children, it's hard to get them to trade a pin that they like. So for my daughter and nieces, I buy pins that I know they don't like, such as villains. My DD is just getting to the point where she gets the concept of putting together a collection. So, since her favorite character is Ariel, she now only trades for Ariel pins.
For older kids, I'm sure it's fun to build a collection with some favorite character or other theme. And for kids who like to research things, sites like pinpics.com and dizpins.com let you look up pins that you have to see where they are from or how much they're worth.
In addition to certain vacation packages, you may also be able to get free pins at one of the big pin trading stores. There's one at
Disneyland, and when we stopped by they had a little presentation for kids about pin trading. When it was over, each kid was given two pins. I think there are one or much such stores at the WDW parks and they might have a similar presentation. I don't know what the max age is.
