One of the things we collect are money boxes. These are two of my favourites.
These money boxes are small replicas of what the Danish and Swedish postboxes once looked like. I don’t have the keys so there’s not actually any money in them.
The red one is Danish and says “Herein you may not place false money, empty as you please’ and the yellow one is Swedish and says ‘He who saves is not without” (or literally: he who saves, has).
