Mining Institute Graduation Badge.

[EricFG]

I've seen described as:
A) Russian USSR badge given for Graduation in the Mine Geological University. Made from solid metal with enamel.
or
B) To Excellent Worker of Competition of Coal Mine Industry. People's Commissariat of Coal Mine Industry.
I think more like the former than the latter.

Anyway, I just got this after much handwringing as the seller made no sort of communication whatsoever after accepting my second offer.
The first image is the 2 foot length of electric tape wrapped around a paper towel that the seller passed off as packaging. :( Thankfully there was no damage.
Nice quality in any event. Two piece as well!

#2813 in A8 on page 563.

"Горный институт знак выдавался выпускникам ряда вузов"=
The college of mines, a sign stood out to graduates of some high schools
or
The Mountain Institute, a sign of a number of university graduates was issued.

So mining/geology college/higher school/insitute graduate badge.
