Value of NOS Remington 1100

My father gave me a New 1100 he bought in mid 70's it is still in the original box with the original packing foam and owners manual.Never been shot, his hunting buddy got sick and it sat for 30+ years.
The serial number on the box is N 612666V and has vented rib barrel
I would think this is a rare example of this model gun being it is essentially NOS.
Thanks Mike

BTW it is a 12GA.

id say your 1100 would bring 500-650 in the box,,
