Items appraised include an ancient shekel of Tyre; two original Duesenberg presentation drawings; a pair of engraved 1860 Colt Army revolvers; and a case of 25 cans of 1962 military emergency water, which was found under the floorboards of the decommissioned Peacekeeper missile launch control center at F. E. Warren Air Force Base by the seller's contractor father. Andy, the shop's head of security, later informs the Harrisons that the shekel, for which Rick paid $1,600 and which he sent away for authentication, may be stolen, requiring it to be put on hold.
