Vintage raleigh price and year?? Please help :)

[matisse]

Hello! I have a vintage Raleigh bike that was given to me by a friend and I am trying to figure out what year it is from and how much it would be worth, can anyone help me?? 

There are two serial numbers on the bike (these are the only one that I have found): one says 59239F and the other one says N55106895 I think, it has faded out a bit.

The gears are Sturmey Archer and it has a faded sticker that says "Oliver Somers, Wigan".

It is not in brilliant condition but I reckon it could be quite old! It also still has the original leather saddle.

Oh by the way, it's a Raleigh Superbe

Judging by the cotterless crank and the reflectors it's mid 1980s , frame number works out as 1985
