Well I hate asking for the value of a gun in the tech forums but I figured if anyone knew, it would be you guys.
My dad has been on a classic rifle kick lately and picked up a couple of old German weatherby rifles and now this,
a pre 64 Winchester model 88 in 284win.
Rifle is in good codition, metal is 90-95%, wood is 80-85%.
It has one mag, and is topped with an older Leupold Vari-x II 3-9.
I’ve done some reading myself and apparently the pre 64 88 in this caliber is one of the more rare ones.
Any help would be greatly appreciated! I have a couple of pics if anyone needs to see it to help me out with a value. Just pm me your number and we can chit chat.
THIS IS NOT A SECRET “FOR SALE” THREAD!
Just one gun nerd reaching out to more gun nerds that are more knowledgeable in this area.
Thanks guys!

I'm looking at completed auction prices on GB where Pre-64 Model 88s actually sold:

Pre 64 Winchester Model 88 Rifle .308 Win w/ K4 scope (about 90%) - 1 bid, $750
Winchester model 88 pre-64 .308 1960 (about 80%) - 1 bid, $659
9243 Winchester model 88 308 Win pre 64 (90%) - 1 bid, $700

There are also listings that did not sell (three of them are the same rifle):

Winchester model 88 Pre 64 nice 1959-1960 308 90% - starting bid $579

Winchester Model 88 .243 Pre 64 - 6 bids - $560, reserve not met.
Winchester Model 88 .243 Pre 64 - 6 bids - $810, reserve not met
Winchester Model 88 .243 Pre 64 - 9 bids - $859, reserve not met

Winchester Model 88 .243 Pre '64 (98%), Redfield 2-7 scope and spare magazine - $949 starting bid, no bids.

In terms of current auctions, with the exception of the above mentioned .284 with a starting bid of $2,349 (and no bids with only 20 hours left on the auction) the highest "buy it now" price is $1,350 for a mint condition .308, with another .243 at 90+% with a buy it now of $1,100. And no one's biting on those.

The least common calibers are the .284 Win and the .358 Win.  The Model 88 was originally produced in .358 Win and was discontinued in 1964, so all but a single year of production of .358 Win Model 88s was pre-64.  The .284 Win was introduced in the Model 88 in the middle of 1962 which means there was only a year and a half of production of pre- 64 .284's in .284 Win,  which makes it a fairly limited production item.

However, based on current market values, asking even $1500 is probably asking too much unless it's in near mint condition and you can find an interested collector.  That could happen with an 85-90% Model 88 in .284, but I doubt it.   In that condition, your target market is a hunter who really wants a Model 88 and really wants one in .284 Win.  At a minimum you'll probably need to list it repeatedly before you find someone that wants it that bad.

A better bet if you want to move it quickly is start with a low initial bid price around $400, set a $1,000 reserve and a 10 day auction and see if you can get enough interest to get a bidding war going.
