I wrote to Ron Delnevo and asked him about his article, and his response followed.
One of the great problems everywhere is the secrecy surrounding all things ATMs and cash. The less the public is told the better, seems to be the the general view of the "authorities".The Swedish 1000SEK banknote designs

So the circulation of this note dropped from 40+ million to just under 10 million in 7 years. The Riksbank argues that the general public did not want the bills anymore.
But did the government produce 40 million bills with motion sensor strip and destroy them , or did they only produce 10 million bills with the strip?
If the former case is true it lends credence to the idea that the public rejected the higher denomination. However, if the latter is true, then the government was trying to phase out the 1000kr banknote.
By keeping production quantities a state secret nobody knows the answer.
Similarly the Hammarskjöld banknote is circulating in such small quantities as to be nearly invisible. Nobody know how many (if any) are in storage.
