On the bid screen, each auction participant enters the maximum dollar amount over the lien face amount that they are willing to pay. This dollar amount is referred to as a "premium". Bids must be entered in whole dollars (no cents). To enter a bid at face value, you would enter a $0 premium amount. At the closing of each batch, the auction software evaluates all bids and the lien is awarded to the highest bidder provided he or she has a sufficient amount of deposit with the county at that time.
