Q: This stein is marked with a picture of a castle and "Mettlach -- VB." Under that mark is the number 2122. Could you please let me know if it has any value? I have been curious about it for a long time.
A: Your stein was made in Mettlach, Germany, by Villeroy & Boch during the late 1800s. Originally it had a pewter lid with a porcelain insert. In its original condition it would be worth about .. $3,500. It's impossible to assess the diminished value due to the missing lid; you are at the mercy of any potential buyer.
Q: My doll looks just like a newborn 0l baby and has the attached mark on her back. Can you tell me anything about who made her and if she is valuable?
A: "Baby Betty" was a trademark used by the Butler Bros. on dolls manufactured by Armand Marseilles in Koppelsdorf, Germany. The first Baby Bettys were imported in 1912. In good condition, your doll would cost $500 to $600.
Q: I have read that old Coca-Cola trays marked "Vienna Art Plates" were worth several hundred dollars. What about similar trays not marked Coca-Cola?
A: The Coca-Cola trays sell for $400 or $500 and the trays without that logo sell for about one-tenth as much. Such is the power of fame!
Q: I have a vase with a pear-shaped body and a tapered neck. It is 14 inches tall and is decorated with birds and flowers. The mark is "Imperial Amphora, Turn, Austria." When was this made and what is its value?
A: Your vase was made by Riessner, Stellamcher & Kessel in Turn, Austria, in the early 1900s. It probably would sell for $165 to $185.

Her dress is in shades of green. She is on a black base and measures 6 1/2 inches tall. I also would like to know when it was made.
A: Royal Doulton made this figurine in Burslem, England, between 1931 and 1938. It has sold as high as $1,500 in good condition.
Q: Several years ago you wrote about china marked "Tunnicliffe." I picked up a small covered jar with this mark. It is blue on white with gold trim. Can you supply any information about this?

Q: What can you tell me about my covered jar? It is 9 inches tall and 6 inches in diameter. It is reddish brown and decorated with grape vines. It has stubby handles on each side near the top and is marked "Weller Pottery."
A: Your jar was made in Zanesville, Ohio, during the 1920s and would probably sell for about $125 to $150 in an antique shop.
Q: Is there any value to an old postcard advertising Campbell Soup? It shows four children, one dressed as a chef. It is imprinted "Campbell Kids" and "Campbell Soups -- 10 Cents a Can."
A: Cards like this are very popular with collectors. This was made about 1920 and would probably sell for about $25 to $35.
Q: I have a sterling silver bonbon spoon that is marked with a crown, a "W" and a lion. It is also imprinted "Wall & Daugherty of Honolulu." The bowl is a cutout flower and the handle is a cutout "Honolulu." Can you tell me anything about this spoon?

Q: We discovered a bound volume of Harper's Weekly (January to June 1863) in the attic of an old home we acquired. It is in good condition except that is dried out and the pages are brittle. There are pictures and articles about the Civil War. I am sure that this is valuable. What can you tell me about it?
A: Your bound Harper's Weekly is worth about $250 to $350 because of the Civil War material. That's about twice the value of a similar bound volume published before or after the Civil War.
