Beretta 92 FS Stag Grips-Worth What?

As I was searching through a box of grips that I had misplaced 7-8 years ago, I thought I had a pair of Stag grips for a Browning Hi-Power, but I found a pair of absolutely beautiful Stag grips for a Beretta 92.
New and perfect and unbelievably heavy.
Nice grain.
A friend is interested in them.
I've heard that Genuine Stag is no longer imported, what might I ask for these and be fair?
