Zion Canyon Utah 100 Years Commemorative Lapel Pin For Sale

Zion Canyon (Utah) enamel pin, approximate measurements 1" x 1".
The pin says "100 Years" so it's some kind of an anniversary pin, but the numbers are too small and blurry for me to read. One possibility could be 1909 to 2009, as the canyon was declared a national monument in 1909 (Zion National Park opened in 1919).
This is a pre-owned item and sold as is. Both the front and the back of the pin seem to be in good condition, but the butterfly clutch feels a bit stiff.
Please have a look at the photos for details.
