Q: I inherited an antique doll I was told dates from the 1800s. It is a 21-inch boy doll with a cloth body. I think the head is bisque. It’s marked “Effanbee.” His features are painted on. He is wearing black pants and a tan jacket that has buttons with the word “Effanbee” on them. Is the doll valuable?

A: Dolls marked “Effanbee” were made by Fleischaker & Baum (F & B) of New York. The company was founded in 1912 by Bernard Fleischaker and Hugo Baum, so your doll is not as old as you thought. The mark can help you date your doll. If the word “Effanbee” has a capital letter at the beginning, followed by lowercase letters, it is an early mark. All capital letters were used beginning in 1923. After 1923, the middle letters, “an,” were written in smaller capital letters. The company changed hands several times and is now owned by Tonner Doll Co. of Kingston, N.Y. If your doll is in fair condition, it’s worth about $200. In mint condition, it might sell for $500.
