For what it's worth. Brass is worth as much as people are prepared to pay for it!!!!!!!!!!........Norinco brass......you may be lucky and find someone willing to pay up[ to £10/100; probably not!! Most once (???) - fired commercial .223 brass commands about £10-25 per 100. (Bearing in mind that "Once-fired" might not really be that at all!!) Once fired ex-mil stuff like RG, GGG, or IMI normally goes for £10-£15 per 100.
Your IMI (Israeli) and your PMP (SA) cases should be OK for reloading if they're boxer primed which they probably are. Only real issue with ex-mil cases is the Primer Crimp which takes a wee bit of time to remove. 3 seconds each with a battery drill operated countersink tool will do the job easily.
