What is the value of a peavey model njac-98 guitar?

The Peavey NJAC-98 is made in Korea at the Unsung plant as a "USA Custom Order" item (the "NJAC" code stands for North American Custom Shop, though the guitars were never made in the US itself), they do not ship with any papers (COA's included), or have any special case and they typically go for just over $489 USD or best offer on Reverb.com
