Rare jadiete piece sold at auction

I recently sold a rare Jadeite piece I didn't know how rare it was. Until I found it in an old vintage book on anchor hocking fire king identification and price guide.  It was a large 11-inch Swedish modern mixing bowl.  As soon as I placed it on auction I got offers on it, I accepted 50.00 on it because it had a small chip and crack on it.  I sold it as is.  This example was very unique sold it for a client.   Here is the photo of the mixing bowl.
