doubs43, you're thinking Yugoslavian, not Romanian.
Romanian SKS serial numbers consist of AA1111, with a two letter prefix and a four number, arabic numeral suffix. On left receiver, date of manufacture, e.g., 1959, appears directly after serial number. Stock finish is generally dark gloss lacquered. Arrow-in-triangle proof should appear on left of receiver. Triangular cartouche may appear on buttstock. Rear sling mount on keel of buttstock. Minor distinct characteristics in rear sight -- "I" at base of calibrated range. Folding blade bayonet. No grenade launcher or sight. Standard length cleaning rod.
Romanians are THE BEST SKS. Heroes of the Revolution of 1989.
As to price, I paid $139 for mine in 2000, but I'd pay $350 for a nice one now.
