Canadian Coca Cola Sign

Hi, folks. Long time member here with a focus on clocks. I'm trying to determine if this is a rare sign. I am doing estate work and can't find any other examples for which to assign a value. I realize asking for a value is not allowed. So I'm not asking for value, just an idea of whether or not it is a rare sign compared to others of similar size, shape, etc.

There is small writing on the bottom indicating it was made in Canada.

I have not removed it from the wall, but the back side feels smooth, so I believe it may be double sided.

Thanks for any help!
