Where can I get a first edition newspaper valued?

[sleepyhead08]

I have a first edition of the Sunday Correspondent, it is number 0001 dated September 17th 1989. All I can find out is the paper started on 17th Sept 89 and finished in 1990. The problem is I don't know where to begin looking for a value.
