✅ SOLVED Some what is its

[fyrffytr1]

I received a package in the mail today from my brother and it was crammed full of all manner of small items from flat buttons to suspender parts to a few buckles. It will take me a month to go through all of the stuff. Here are a few that I could use help with. I didn't know what the first one was until I edited the picture of the back and saw the reverse letting that read Dick Tracy on the badge with something else right under it. Then the word sergeant appeared in the chevron below the badge. Any idea on age?
The second one is a brass buckle(?) that came from my late brother. There are no markings on it. There are some small marks on the back but I think they are incidental damage from whatever this piece went on. My brother thought it might be a cross belt buckle?
I'll post some more next chance I get. Thanks for any and all help.

The second object is a Morseman's Patent buckle-shield (a.k.a. buckle-cover). Instead of re-typing all the info and re-posting the photos, let me ask you to please view my post on the Morseman buckle-shield about a week ago, here in the What Is It? forum at the following link:

Ones made before Morseman's patent expired (which happens 17 years after the patent was issued) are marked "Patent Dec. 16, 1879." If yours lacks the patent marking, it was made after the 1896 expiration of the patent.

Thanks for the quick and accurate identification. For some reason, my late brother thought this was something significant. He passed many years before the internet but he would have been posting some awesome finds if he had lived.
I am pretty sure that the Dick Tracy badge dates to the 1930s so I am marking this one solved.
