If you use a piggy bank as an interest-free savings account, you're probably happy to wait and be surprised at how much money you amass. But if you instead use a piggy bank as just a place to store pocket change, this simple weigh-scale bank will let you know when you've got enough money to buy a coffee or bagel.


Designed by Selma Durand as a master's project for her design school, the bank features dollar amount markings on the inside of the ceramic container that are revealed as the inner brass bowl sinks under the weight of coins. Unfortunately you can't buy one—at least yet—and it's calibrated for Euros which means those outside of Europe will still be left guessing as to whether they can afford a Starbucks coffee or a McDonald's.
