I see that the reverse has the corporate name "Palmolive-Peet Co.," so presumably it dates c. 1926-28. The company was formed in 1926, when Peet Bros. merged with U.S. Palmolive. Two years later, Palmolive-Peet merged with the Colgate Co., forming the Colgate-Palmolive-Peet Co. These tokens generally go for $2-5 in average circulated condition. The highest price I've seen is $25 for one in Uncirculated condition, and I have a hunch the dealer may own it for a long time!
