Yes. A few weeks ago, at an NFL playoff game, they had a coin toss, and the GB Packers contested the coin toss because the coin did not "flip". Also, I believe the coin is always shown, both sides, to each rep, so that they know it is a legit coin with heads and tails.
Anyway, the ref determined that the coin did not "flip", so the toss was redone.
I'd like someone in Vegas to give me the odds of the same party winning six separate coin tosses.
1998 NFL Thanksgiving Day Game: Pittsburgh Steelers vs. Detroit Lions: This controversial call changed the game of football forever or at least the coin toss. The Steelers and Lions were tied and the game was sent into overtime. The coin was flipped midfield and, according to Steelers RB Jerome Bettis, he called tails. The coin landed tails side up and the referee declared the Lions the winner of the toss.
Confusion erupted. Bettis screamed at officials that the referee had gotten the toss result wrong. Referee Phil Luckett, the official who declared the toss, later told reporters that Bettis had called ‘’heads-tails’’ and Luckett, according to NFL rules, went with the first thing he heard out of Bettis’ mouth. The Lions went on to win in overtime and Steelers fans have never forgotten.
No one will ever know if Bettis said heads or tails first, but the rules regarding the coin toss have been since changed to avoid any further controversy
