This is the booklet "If Crisis Or War Comes" which Sweden just distributed to each of its residents. The booklet has been issued 5 times since the end of WW2
My final question in that comment is very sarcastic. I know absolutely nothing about Swedish money but I can guarantee you that it does not expire.
Assuming you're serious, and you have no idea what your own currency looks like, could you not just go to a bank and make a withdrawal in cash and keep it somewhere safe? You don't really need to know what it looks like as long as you get it from a trusted source.
