Estonia is getting rid of its currency and adopting the euro, and this is the last week Estonians will be able to use their kroons to buy stuff. That raises a question: After people trade in their old kroons for new euros, what do you do with the kroons?

Kroon coins are being bashed out of shape and either turned into euro coins or sold to other countries for making other currencies.
The kroon remains a valid currency in Estonia, along with the euro, until midnight on Friday. But by Monday evening 80 percent of cash purchases were already paid in euros.
