CHARLESTON, W.Va. -- A trio of coins is stirring some interest in the West Virginia treasurer's office online auction of unclaimed property.The U.S. Liberty coin set has attracted five bids in less than 24 hours, which Treasurer John Perdue said is an unusual amount of activity.The set includes a dollar coin, a $5 gold piece and a half-dollar. The bidding was approaching $500 on Thursday for the coins, which were minted in the 1800s.A couple other items are also generating high bids. Both are surveying lasers, and each opened with high bids. One bid was $325, the other $475. Perdue's office said those are steals, when compared to retail prices.
