Hey Nanoc,
As Mike has said condition is pretty much everything, that and also the specific team and player will drive the price as well.
I can tell you that the St George 1st grade 1966 Daily Mirror Photo is collectible and would be worth about $15.
The Scanlens league stickers could be a little gold mine if they are 1985 about $10+ each ( still need a few myself) or $2-$5 other years.
If you have no luck with a listing on here I would suggest put them on Ebay during the season to maximise the number of eyes that see your auctions.
Good luck
Ross
