Welcome on board Mick, uploading photos with your descriptions is the best way IMO if your not sure. If you don't know what they are worth I would simply ask for opinions or search then browse some of the older threads, ebay is also a good place to start to get an idea on value, there are also a couple of members who have catologues which offer an opinion on price as well , I think with the Rugby League around that era if you have authentic Albums then they will be of great interest to many and any signed cards always score a premium as well.
Enjoy the site for a while before listing your for sale and you never know you might get the collecting bug back.
Cheers
Ross
