I know this doesn't help but that is a really good condition coin for something so old.
That's one of the really cool things about large cents. You can get really old coins for relatively cheap.
I've researched this coin for about 20 minutes. It could very well be an N-27. Large image here.

http://www.early-copper.com/coinpics/50n26b.jpgI'm inclined to say N-26 because of the position of the point of the curl to the 8 and the fact that the 0 is even lower than the N-27.
Both coin's rarity is low R.5.
Looks like you have another coin to send to Bob Grellman.
Either variety is very cool.

As far as grade I'll agree with the seller's VG-10.
1850 N-26 R.5 10/10
