THis is a great register for teaching money concepts.  The pretend coins and bills are very close to real money, but without the germs.  The register is sturdy enough, and the buttons are big enough for little hands.  Both my kids, ages 4 and 18 months love this toy.  It is their favorite Christmas present.  I like having them play with the pretend money, rather than the real money that is so filthy.  A great buy for budding accounts!
