Value of Old Programmes

[Dackers1]

Not sure if this is the right place for this or not so please move if not.

I recently found a bunch of old programmes at my Grandads house. I am hoping to keep them in the family but have been asked to explore the value of them. I have tried to google it but have not managed to come up with much info.

I am wondering if anyone on here can give some advice. The programme details are below with photos:

Southport 1945
3 programmes 1946
32 programmes 1947/48 season
11 programmes 1948/49 season
14 programmes 1949/50 season
47 programmes spread across 1970/1973
As well as some Away Programmes from the 1940s.

If anyone could shed some light on the specific programmes values etc would be greatly appreciated!
