Horse related.
Hook . Not quite a singletree hook .
But your piece has two hooks also...

 

[ConceptualizedNetherlandr]

Scale? Looks like those bra hooks I always struggled with. Can't tell fer sure, never saw them in the light

 

[Blackfoot58]

Most likely (IMO) an end hook from a gag chain.

Or, less likely, a type of a team pad hook.

Either way, a piece of harness rigging. 👍🏼

Maybe a cheap ring......?

How about a ancient viking Amulet

 

[Mud Hut]

if the 1.5 inches you reference is the overall length, it would be too small to function as anything related to horse tack.

Word to the wise, pictures with a ruler and a coin for reference will help with identification.
