Q: I found an interesting object at a local yard sale. It’s a miniature Empire State Building with a thermometer in the front. It’s 6 3/4 inches tall and is made of plated metal with a golden patina. I paid $1 for it. Is it worth more than that?
A: Lots of souvenirs have been made of the Empire State Building since it was built in 1931. It was the world’s tallest building for decades. Your souvenir thermometer was made in the mid-20th century. Souvenirs like yours usually sell online for $10 to $20, so you got a good deal.
