WW1 US Collar disk. NJ forest dig

[Scrappy]

Found this in the middle of a forest near the edge of an old retirement property. Has the threaded screw but no backing.

Does anyone know the dates of production?

As the examples in the photos at the following webpage show, your US Army collar-insignia disc dates from 1910 to 1924. Note that the outside edges of letters are "long" flat angles, instead of curved. Also (and MOST importantly), your disc has the Type 1 attachment-form on its back. Also note, the front's "background" was changed from tiny dots to diagonal lines in 1924. Compare yours with the photos here:
