Coleman is set to be rewarded for this season's form with a new contract.
Howard, who has been a teammate of Coleman since 2008 when the full-back was recruited from Sligo Rovers, said: "He's a hard worker and a humble guy.
"He works really hard and is his own worst critic but he is everything you could ask for in a teammate and professional.
"When you see a guy get rewards like that it's special and means more because you know he deserves it and he is not going to take it for granted.
"Seven goals is brilliant from a right-back position."
