What's It Worth??? - Mopar Performance 360 4-bolt Main Cap Package

Cleaning out the garage today and found something I forgot I even bought for my Dart project. I opened the box and they look brand new:

Mopar Performance (PN P5249675) 4-bolt Main Cap Package

This item has been discontinued by Mopar Performance.
My build direction has changed somewhat and I'm not sure I'll be hanging on to these.
What's the value if I decide to list them?
I will post pics if I list them.

Thanks in advance!
