55mom and RJM,
I don't know how much a Head baseball coach in your areas make, but, I do know what they used to get in our area which was $2200. per season which at 18 to 20 weeks of practice and play which works out to $110. to 120. per week which at a mininmum of 4 hours a day 6 days a week thats about $5.00 per hour give or take. They can make more than that a McDonalds.
I agree with coach 2709, Most coaches don't want gifts, but they do enjoy getting a plaque with a team picture on it. Yes, it is a gift of sorts, but, is usually given by the team leaders, not by a parent or group of parents.
