Cannot find many details at all, apart from the fact that is an athletics award, fixed lightly to the backing in the padded cardboard holding case.

Case is about 5" x 4" and the rectangular award is about 4" x 1 3/4".  It think it is fairly light, and possibly has a hollow back to it.

I have not removed it to see what is on the back, as it is stuck in and I do not want to damage it.

It does look like silver, but I cannot be sure. If not, then it is very well plated and looks perfect.  Case is in VGC too.
