Up for sale is a Port Townsend, Washington WA Hubba Hubba Good For 5¢ Trade Token
This seems to be a scarce token to find. The last sales comp I could find was in 2016, when one sold for $78. For some reason this business name makes me think of bubble gum. Maybe that's Hubba Bubba though :)
Hubba, hubba is a North American informal exclamation used to express approval, excitement, or enthusiasm, especially with regard to a person's appearance (Wikipedia).
The token is made of brass and measures 21mm in diameter.
