SK prices vary widely.
At the Indy-500 Gun & Knife show six years ago I bought four SKS carbines for $375. If you wonder which of your guns to retain or to sell any of yours, here are some valuable hints: look for Model 45 guns with the following details: Russian "TULA" mint mark in the bolt cover (may triple the $100-or-less price you paid); 2 cross-bolts in the stock: one in fore-grip, and a second right under your palm when you are firing; all furniture has matching grain and finish & same serial #, and all through-pins are brass, not steel. Also same ser. #on tool-kit, both pieces of the bolt, bayonet-shaft, gas-tube, trigger-group, magazine ( ten rounds: do NOT install a Flash Gordon ultra capacity "banana-clip" on an older original-type SKS unless you want to lose half the value of the original when you sell), a sling-mount in the stock that is set in to run parallel with the grain, not across it, or that has a hole that is puttied over (the early Mode; 45 guns in Russia had this parallel sling-mount design). Also, if you know how to look, check for a threaded-in barrel, and not a pinned-barrel. The "TULA" mint mark is rare on guns that are not Model 45. Other factories began later production models, and TULA changed to non-gun products, except for about 500 or 1000 guns. I have one of my four left, and sold the others for $700 each. The one I kept is worth well over $1000. I see some TULA guns occasionally at shows, and the prices are high if the seller knows what he's got. Keep looking and you'll find that cherry you want.
