NOTE TO SELF: If I ever become an auctioneer, change my last name to "Riches." LOL.
I was once at a Saturday morning auction at the old Lubin Galleries on 25th Street in NYC. They were selling lots of old junk, nothing more than $50 or $100, when a Persian tile estimated at $50-75 came up.
It sold for over $9000. Evidently, several of those present knew what it was. The auction house sure didn’t!
