Condolences on the passing of your brother Jay.
Unfortunately programmes from the 60s onwards are not worth much as they were mass produced, especially Man U !

Hibs wise, games where George Best played are worth a few quid , the 7-0 game obviously, and a few postponed issues are also very collectible and valuable

You could take them to Brian at Almondvale Programmes in Albion Road and he would give you an idea on value. You could also possibly bundle them up into seasons and try your luck on eBay

Condition is also important. If they are folded, creased etc then they are virtually worthless
