Below is an interesting question that was recently asked about some collectible mugs. The answer gives a glimps into the research needed to answer these type of questions.
Q.What are my Schultz and Dooley mugs worth?
One is tall, with blue flowers around the body and a mustachioed face on the lid. The other is short, with a green shamrock painted on the front.
A. Schultz and Dooley were mug-shaped characters in a series of early TV commercials for Utica Club beer, which was produced by West End Brewing Co. (Webco) of Utica, N.Y.
The black-and-white commercials aired in the Northeast U.S. from 1959 to 1965, and increased beer sales and won awards.
The brewing company contracted with Schmetzer Inc., a New York importer, to buy 5,000 sets of ceramic mugs based on the advertising characters. The mugs were made in Germany.
The original mugs can be identified by their marks. Schultz, the large "German character" mug, is marked "The West End Brewing Co., Utica, N.Y., 59-CSM" in blue letters under the handle. Dooley, the smaller "Irish character" mug, is marked the same except "59-CDM" and in green. The bottoms of both are impressed "Webco, Made in Germany."
A pair of these original steins sells for about $300 to $500. Schmetzer imported thousands more of the steins during the 1960s, but these do not have the "CSM" or "CDM" marks. They sell for less, perhaps $50 a pair.
