The last I heard, experts were trying to restore it for sale at Cristies' or Sotherby's. I was too jealous to follow the story further.

Or not really. I feel I might out of guilt, but would somehow end up being sued by the seller.

So maybe it’s best not to.

opportunity to find out what it is. Plus, in this case, $35 for a bowl at a yard sale is a high price unless the seller thinks it has some value. There was a case not far from where I live where people were working as "volunteers" for a church collecting donations for a charity auction. A lady donated a painting and the "volunteers" (one or all, I forget) thought it might be worth something and took it to the city to a well known auction gallery for evaluation. The painting was valued at about $400,000 as I recall so instead of taking it back to the lady who donated it, they waited for the auction and bought it for about $3,500 and later sold it through the auction gallery. I think I have a memory of a lawsuit in that case, but in that case I think it would have been justified.

Found a badge kind of thing that I had no idea what it was. Had a advertisement on one side and a rock like surface on the other. It was a hook/knife sharpener. From a local store ca.1920.
Got it out of the free box and donated it to a local museum.

Now I'm really chomping at the bit for yard sales to start up. (Sold price includes buyer's premium. Purchaser unknown.)
