Best state quarters holder/display?

[overcome]

All 3 kids have a complete collection of state quarters so I want to get a holder/display. I've seen them in ACMoore, so I could use a coupon, but I'm wondering if I should be looking for anything special.
ETA I'd like one that utilizes a map.

Bumping because I have the exact same question.
I got my mom to save 3 sets for the kids. Poor thing, now she'll have to do a whole other set :D.
