If I remember correctly, they should be 500 RMS- 750 Max. The LVS were the top end subs of that era (pre-Mojo). As far as value goes, I wouldn't expect much for 10 year old subs.
They were the replacements for the SHP's... they were competitively priced for the time (around $300) but now they would be overpriced for what you get. If they are the dual 4 ohm version, I would put a pair on 1100-1200 watts RMS at 1 ohm.
