With regards to this season's programmes, the Norwich one isn't going to be worth a great deal as they sold thousands.
I was up at St James Park on the Saturday morning and no programmes had been printed for distribution to the public because Newcastle don't print until the night before and the game was called off on the Friday morning
The postponed games vary in value and much depends on the opposition, as my mate Spongebob alluded to, the Norwich v Southampton game was fetching £200 plus, but as in these things prices then tend to drop and are now in the £70-£80 bracket.
other games like Brighton v Arsenal between £6 and £10, Hull City v Charlton £10-20, a lot of games lower down the pyramid around a fiver.
Of course there will be collectors who will want them all
If there wasn't a programme produced, then tickets will have value, Spurs v Manchester United £50 plus, this, on the main will be spurs collectors as the only tickets available were distributed to away supporters only.
