Stainless steel Rally beauty rings worth anything?

[71CHEVYSHORTBED402]

or are these another memento? They're in real nice shape. Shouldn't require much effort to restore them to new or close.

Three are stamped, which I assume is a date. One isn't stamped, and the rivets on the clips are brass color. Other than that it's the same ring. These are for 15" wheels and are 1.78" deep. I bought them with the wheels, sometime during the early 90s.

Thank you.
