Depending on condition, type of barrel, sights, etc, anywhere for $150-$300.
Try including the caliber, barrel length, sights (if any) and serial number (minus the last three numbers, which should always be indicated by x's).
Value is driven by exact model (you did not say) and condition (you did not say). So we can't really say. It could be $100 for a well worn Mk1, or $450 for a like new MkII with a select barrel and sights. Stainless or blued also makes a difference in price.
