For everyone who has asked. I am located in West TN. I haven't finalized a price, but one just ended on Gunbroker for around $2000.
I had one in 1973. Bought it new (my dad did the paperwork) from pushing groceries. $175.
I even wrote Remington and asked them if they were going to discontinue making 16's. Of course they said no. I killed A LOT of quail and later grouse with that shotgun.
Later sold it in Lnoxville at a gun show.
One thing I noticed about yours AND mine is that the receiver is only cut out 2/3rds back as opposed to others where it has a thinner cutout that almost goes to the back of the receiver? Never knew why.
Good luck on the sale.
