A: You have a jardiniere and pedestal that was made by Robinson Ransbottom Pottery in Roseville, Ohio. They have produced kitchenware and stoneware since 1900.
Your stoneware set was made around 1920 and would probably be worth $275 to $375.
Q: This mark is on the back of an oval porcelain platter that was given to me by my mother-in-law. The platter has a green border and in the center there are sprays of pink flowers and greenery against a white background. It has no chips and is in mint condition.
Do you have any idea of who made it and what it's worth?
A: Remy Delinieres Co. made your platter. They have made porcelain in Limoges, France, from around 1879 to the present.
Your platter would probably be worth $75 to $125.
Q: I hope you will be able to help me to learn more about a doll that belonged to my mother around 1915. She stands 15 inches tall, has a composition body, jointed limbs, a bisque head, and an open mouth with four teeth showing. Marked on the back of her head are the words ''Armand Marseille - 390N - Germany - AM.''
A doll restorer restrung her limbs and replaced her wig. She also replaced the sleep eyes with permanently open eyes. Other than that, my doll is in very good condition.
What can you tell me about its value and maker?
A: Armand Marseille Doll Co. was one of the leading suppliers of bisque doll heads for factories that made doll bodies. They were located in Thuringia, Germany, from 1885 to the 1930s. ''390N'' is the model number of the doll's head. In the early 1900s when the Armand Marseille factory was operating at peak performance, they produced at least 1,000 heads a day.
The value of your doll would probably be $190 to $255.
A: Wagner Ware made your cast aluminum roaster/Dutch oven. They are located in Sidney, Ohio, and make cast iron and cast aluminum cookware. ''Dec., 10 - 20'' is a 1920 patent date and ''No. 8'' refers to the size.
The value of your roaster would probably be $25 to $50.
