I thrifted this tin can at a flea market. It's a teaching aid to help kids learn to calculate money, more specific coins. Before the Euro the Dutch currency was the Dutch Guilder. The coins were 1 cent, 5 cents (stuiver), 10 cents (dubbeltje), 25 cents (kwartje), 1 guilder, and the rijksdaalder which was 2,5 guilders.
Now that my kids receive pocket money and learn to calculate I realise how difficult it is for them.
