does it have a spike bayonet? and does it have a stripper clip? IF its got all that and is AK mag compatible then you could look to get around $350+ i've seen em even for as much as like $550+ ( also mint condition though) i've also heard them without the bayonet or the AK mag compatibility for as cheap as $150. but yours is pretty set.
Its funny how the chinese make their stock on the SKS shorter because they're all a lot shorter than the albanians, romanians, and russians
I personally like the Norinco sks sporter with the even shorter thumbhole stock but im a CQB junky ( i like my firearms all compact and travel size for you convenience. even though its completely nonsense for a rifle like this.)
