Yes, the need to have a coin is becoming problematic in Sweden where cash is rarely used for anything. I make sure I have a few 10 kr coins in the car for use with supermarket trolleys, though many of them haven't been changed to accept the new smaller coins so I also have an old large 5 kr coin. These are now no longer valid and you can't even change them at the bank, so in effect it is a token along the same lines as various obsolete or foreign coins were repurposed as tokens in the 19th century. The difference is that my 5 kr is unmodified, whereas many of the older examples were stamped with their new owners' names, e.g. the common "PEAR'S SOAP" on French 10 centime coins or "ALLAN DAHL" on Swedish 5 öre coins.
