(1)   Except as provided in subs. (2) and (4), the administrator, within 3 years after the receipt of abandoned property, shall sell it to the highest bidder in a manner that, in the judgment of the administrator, affords the most favorable market for the property. The administrator may decline the highest bid and reoffer the property for sale if, in his or her judgment, the bid is insufficient. If the administrator determines that the probable cost of sale exceeds the value of the property, it need not be offered for sale. Any public sale under this section held in a city, village, or town in this state shall be preceded by the publication of one notice, at least 3 weeks in advance of sale, in a newspaper of general circulation in the county in which the property is to be sold.

   (2)   Securities listed on an established stock exchange shall be sold at prices prevailing at the time of sale on the exchange. Other securities may be sold over the counter at prices prevailing at the time of sale or by any other method the administrator considers advisable.

   (4)   Unless the administrator determines that it is in the best interest of this state to do otherwise, he or she shall hold all securities for at least one year before selling them. No person has any claim under this chapter against this state, the holder, any transfer agent, registrar or other person acting for or on behalf of a holder for any appreciation in the value of the property occurring after delivery by the holder to the administrator.

   (5)   The purchaser of property at any sale conducted by the administrator under this chapter takes the property free of all claims of the owner or previous holder and of all persons claiming through or under them. The administrator shall execute all documents necessary to complete the transfer of ownership.
