This is the same one I have (from Grandma’s house) but yours is in way better condition. (Mine looks like a dirty old penny. My parents told me you could buy these and either keep them as a souvenir or use them as ride/consession tokens. But $1 in 1962 seems like a hefty fee for either.

During the fair my grandpa paid to take my mom, my grandma and his mother up on a plane to fly over the space needle. It was a special thing you could buy in conjunction with fair tickets. I wonder if they took tokens? 😄
