Vintage Utah One Mill Sales Tax Token, Circa 1940s

Description

The state of Utah started issuing sales tax tokens in the mid-1930s. During World War II, they changed from aluminum tokens to ones made of plastic. The plastic ones were issued from 1942 to 1951. The information available indicates that about 29.4 million of these tokens, in the one mill denomination, were issued. They were demonetized on Sept. 15, 1951. The number melted or otherwise destroyed isn't known. The plastic tokens were manufactured by Rider Engineering and Plastic, Ingwersen Manufacturing Company, and possibly others.
This token is about 22mm in diameter. It is "Irish" green in color. There were three dies used in combination on the obverse and reverse, making six die varieties. These are based on the width of the circles around the denomination and the space in between. The two concentric circles in the center of this token are about 9mm in diameter for the inner one, and about 11-1/2mm in diameter for the larger one. There is the numeral "1" inside the circles. The denomination, therefore, is one mill.
Both sides of this token are identical, and you can flip the token over horizontally to get the same orientation for both sides. (If you flipped it around vertically, one side would be upside down with respect to the other.) There are two dots, one on each side near the perimeter. Above the dots are "State of Utah", and below the dots are "Sales Tax Token".
The color and translucency of these tokens vary as a result of different mixes of the plastic and dye, and from aging.
This token appears to be in perfect condition. It does not show any effects from aging, and there are no scratches or areas of wear that can be seen. Please see the photos.
