Exactly once. On August 29, 1960, France beat Bulgaria 73-72, and no Olympic Basketball (Men) game before or since has ended that way. When it happened it was a scorigami, the first 73-72 in league history.
That makes 73-72 the 126th most common final score out of 698 that have ever occurred in Olympic Basketball (Men). One point away, 74-72 has happened 2 times and 73-73 has happened never.
