Identifying hubcaps

Whilst cleaning out the attic of my late father's garage, my brothers I and stumbled upon a set of hubcaps. Both my younger brothers denied that they came from any of their numerous vehicals over the years, and neither could identify what kind of vehicle or year that they came from.

You can see a pics of a cap at

Any ideas?

I believe those would be from a Ford LTD (not worth much)
