I should also add - make sure your photographic skills are top notch. One of the worst way to get proper valuation of a coin is poor images. The more in a hurry you are to sell something, stereotypically, the less valuation it will get due to cutting corners in your entire process which will devalue it in the eyes of the "stereotypical" buyer.
Occasionally you'll come across a very good deal. Seems like you at least believe you've found one. I would have bought it. Worse case, you're out a few bucks for a nice war nickel. Best case, you triple your money and use it to get an even nicer coin.
I am actually building an uncirculated war nickel set in MS66 and lacking about 5 coins, I haven't paid over $30 for any single coin and they are all PCGS or NGC certified.
This reminded me of people complaining that dealers would be asking too much for a coin and when they tried to deal, were told "Well, I paid such and such for it". The reality of the markets is they go up and down.
Coin blazer. Give it a shot. Its 8 bucks. Worth a try. That way if it doesn't sell. It not a great loss.
The real question is what do YOU think it grades? And the NGC and PCGS price guides are meaningless for coins not in the proper plastic (In many cases they are still meaningless.) If you MUST use them for comparison, add about $30 to the price you would pay for the coin (To get them into the right plastic) and then compare them to the price guide.
