It was a couple of years ago that a well-known family gave the toys, packed in a box that had originally encased ski-boots, to a second-hand store in Ockelbo, which tucked them away.
However, their destiny has now been decided. They will be auctioned off as part of a Swedish Radio P4 Gävleborg drive to collect money next year to benefit children.
Gunilla Brodin, who manages the second-hand store, says that while there is a tacit policy not to talk about who has donated goods to the shop, in this case, the gift was so extraordinary, that the story needed to be told.
Prince Daniel, who married into the Swedish royal family when he wed Crown Princess Victoria in 2010, hails from the northern Swedish municipality of Ockelbo.
