If you mean one still in the factory wrap and cosmoline as turns up from time to time, any figure the seller pulls out of the air might be asked and perhaps paid by some buyers. Apart from their propensity to still turn up unused from time to time they are not very remarkable or special as a collectible. They tend to have a nicer finish than some wartime production rifles but that may be offset in the collector's eye by the fact that wartime production rifles may have been used in the war. So once they have been used it is a matter of how much they were used and how well they were cared for, i.e. condition, same as any other milsurp.
