Bell's Scotch Whisky token from a Scottish Open Golf tournament

Many thanks to my sister-in-law Annette who gave me this brilliant Bell's Scotch Whisky token from a Scottish Open Golf tournament. It's a great addition to my collection of tokens.

One side contains a message to the bearer, the other to the licensee.

To the bearer: On surrender of this medal you may purchase a single measure of Bell's Extra Special for 1 penny. Valid until 30th September.

To the licensee: This medal entitles the bearer to purchase a single measure of Bell's Extra Special for 1 penny. Valid until 30th September.

What a bargain.

There's also no year on the token. I wonder if it's still valid?
