No idea what "ed news custom blend" is, actually.
In any case, "half a tin," likely 50g ot 100g if a full tin, would mean you have roughly half an ounce to an 1.5 ounces of pipe tobacco remaining.
You could (giving a better description of course), offer to trade it for a cigar, or bomb it/give it to someone else who would appreciate and smoke the stuff.
