Chicom AK's are probably like IMI Galil's, not even made anymore. Original style anyway.
Here is a Swiss catalog from 2014 with a Norinco 56S-1 for 650 CHF ($1.02 per CHF today). While that seems high, it's very cheap compared to other gun prices over there. American prices from the 80s probably aren't far off once you adjust for inflation.
