How old is this horseshoe?

[Dirt_Hunter]

Hey guys!
Can you help determine the age of this artifact? The material is iron. This was discovered near an old mill/horse-stable. Unfortunately I cannot determine the age of the location, even the land owners don't know.
Thanks guys!

Hard to date a deteriorated shoe , unless maybe by a particular style .

First you have to tell us how old the horse was.
