What is the name of this piece and is it worth anything to any bus enthusiasts?

[Indiana Motor Bus Guy]

Greetings to all! I'm an old over the road guy who has driven a charter coach throughout the US and Canada racking up about 3 1/2 million miles. Drove MCI's, Prevosts, Van Hools and even an old Flexible with "3 on the tree" if you remember those. I retrieved this front company identifier from Indiana Motor Bus Company in South Bend, Indiana years ago. Came off an MC9 in the 90's.
Wondering what its correct name is and if it's worth anything to anyone?
Thank you guys!
