Checker Motors Corp. donated the cab to the Pate museum in 1979 with a letter of authentication. RM Auctions had said it expected the 1962 Checker Marathon would fetch $20,000-$30,000 in bids.
Oswald hailed the cab after the bus in which he tried to escape got stuck in traffic moments after President John F. Kennedy's assassination. The driver identified Oswald in a police lineup the next day.
