I didn't know where to post this so I'm posting here in Coin Chat. I've read that these were made between 1910-1930. There's a swastiska on the reverse with different symbols. The swastika was a symbol of good luck, that was until Hitler used it and now it symbolizes a totally different meaning. I found this piece cool.
There are several different types of Worcester Salt tokens, with different salt container designs and manufacturers. Manufacturers included token makers Greenduck, Whitehead and Hoag, and Bastian Brothers. The OP's token appears to be a Whitehead and Hoag version. The "Dont Worry Club" is a generic reverse used for many American advertising tokens. There are some on my website.
I found it interesting. For $3, I thought, why not! I didn't buy it to sell it. I bought it to preserve it for future generations of mine to have.
