Date of manufacture from chassis number?

[Sam Fish]

Hi guys.
how do I work out the date my car (or the shell at least) was made? Dont have any paperwork at all, just the chassis numbers and plates.
Hoping its original, and a coupe of course! :dearme:

So I have a 1986 car.

Now, what denotes a 'coupe'?
