It's been drilled and tapped for a scope mount, that reduces value somewhat. Prices on the Yugo M48/98 or MOD98 has gone up in the past year. Even with the drilled receiver I would say at least $200. It does look nice and may bring considerably more on Gunbroker.
I picked this Yugo MOD98 up a year and a half ago for $167+shipping off GB, I think those prices are long gone.
