Nine people have been charged with alleged offenses by Greater Manchester Police following Sunday's Manchester derby at the Etihad Stadium.
Six Manchester City fans and three Manchester United supporters are due before Manchester City Magistrates' Court on Jan. 4 next year.
The home supporter who threw a coin at Rio Ferdinand, however, has not yet been found. The defender was cut above one eye by the missile.
One City fan has been charged with a racially aggravated public order offense, while two more have been charged with pitch encroachment.
Two others have been charged with being drunk and disorderly while one has been charged with a section five public order offense.
Of the three United fans, two were charged with breaching a football banning order and another was charged with being drunk and disorderly.
In addition, four other arrests were made on the day. One was summonsed for a racially aggravated public order offense, while another has been released without charge after being arrested for ticket touting.
A woman was cautioned for being drunk and disorderly and a man has been held in police custody on suspicion of possessing a class A drug.
"To have just 13 arrests for a crowd of this size and a match of this proportion is a testament to the policing operation we put in place," chief inspector Steve Howard said.
"Despite fierce rivalry and high tension there was no major disorder. However, we will continue to investigate the coin throwing incident and are determined to work with the club to bring the perpetrator to justice."
