Q: I have had this embossed self-framed tin sign advertising Grape-Nuts for several years. It is 30 inches high and 20 inches wide. Can you tell me what it’s worth?

A: Grape-Nuts cereal was made by C.W. Post beginning in 1897. The slogan “There’s A Reason” was first used in 1910. Your self-framed sign was made in about 1915. Value: $1,500 to $2,000 if its finish is original. But the paint on your frame looks new. If it was repainted, the value drops by more than half. Enjoy the sign. The first antique we bought was another example of this Grape-Nuts ad. It has hung in our breakfast room or hall ever since. We always wondered what the slogan “There’s a Reason” meant.
