Here it is. It's larger than a half dollar and smaller than an Ike.

Cow ear tag?

 

[ARC]

Livestock tag.

 

[coinman123]

I agree with the above, livestock tag. Probably 1930's at the oldest.

 

[lockster99]

Agreed.

The images on google for cow tags / livestock tags, all follow the same pattern of having a whole in them that then hangs on a earring type loop in the cow's ear. This thing has more of a clip. It probably is just a cow tag, but I couldn't find a pic of one that looks like this.
