M14 Serial Number

Hey fellas. I signed up for this website hoping to talk to someone with savvy on the m14 rifle.
I inherited an older looking m14 rifle. I'm trying to determint e what it might be worth, as it is the type of gun i wouldnt have much use for.
It came with a US army manual dated 1972
there's a 20 shot clip typical of this rifle, and a nice wooden stock with not much wear and tear or scratches
Behind the rear sights are some markings which read : 'U.S. Rifle 7.62mm United States Section of the Milsurp Knowledge Library.', BGCOLOR, '#DDDDDD', BORDERCOLOR, '#000000', BORDERWIDTH, '1',FOLLOWMOUSE, 0, OFFSETX, -10, OPACITY, '95', FADEIN, '25', FADEOUT, '25', CLICKCLOSE, true,FOLLOWSCROLL, true, PADDING, 0, BALLOON, 1 ,ABOVE, false, TITLE1, 'United States - Milsurp Knowledge Library',LINKURL, 'https://www.milsurps.com/content.php?r=132-united-states', SHOWCLOSE, 0, BALLOONIMGPATH , 'autolinker/images/balloons/yellow'); microAjax('autolinker/autolinker_stats.php?uid=0&fid=108&t=v&kw=M14', function (res) {;});'>M14 H&R Arms Co, 71566'
Then another stamp on the bolt itself which reads: ' 7790186
8A Z3'
It's a decent shape, i doubt it has been used much. Does anyone know anything about this gun? I can't do much with it, but do not want to get ripped off if i sell it to a friend who has a license for a gun like this.

The term 'M1A' is a proprietary title for Springfield Armory's M14 pattern rifle, and was first used by the first owner of the Springfield Armory Inc. The M1A is purely designed to be a semi-automatic rifle and cannot in any way be modified to become a fully automatic firearm.
