Metal tag buried in my garden?

I found this buried in my garden. It’s steel, with some flecks of galvanization still visible here and there. Definitely stamped from sheet stock originally, the ring is welded, and it’s especially interesting to me that the right “foot” of the little “table” cutout is narrower than the left one, as if it’s keyed to connect to something in a single direction.

Ideas so far:

• livestock tag (we live near ooold stockyards)
• cremains tag (spooky)
• key fob/id (but why the welded ring?)

Does anyone know what it really is?
