Added info.
I followed Kuger's link and answered in that thread. This item is cast brass, which suggest a belt-buckle, rather than thin stamped-brass. This buckle does have an unusually narrow long "hook" on one end, whose length matches the slot in the buckle's other end, which suggests Mical66 is on the right track in thinking it linked to another one (or more), forming a belt made of them. Or, the unually narrow hook may be a wider one which is partially broken-off. Need another photo of it.
I've seen these buckles saying Georgia, or Mississippi, or Illinois, among others.
Here is what I replied in the other discussion:
It is indeed a belt-buckle. That type has been found showing various state school names. Its specific form is shown in the O'Donnell-&-Campbell buckle-book as a "School [belt]plate." Under a photo of one on page 523, the book says:
"Popular style of early 20th-century School plate marketed by several firms. The 1916 North & Judd catalogue (New Britain, Conn.) listed these as "College buckles." [...] Thomas Parry & Sons offered these as "College Belt Buckles" during the same period."
