Discard tea bags and mint. Pour into a 1-gal. container; add peach nectar, lemonade concentrate, and simple syrup. Cover and chill 8 to 24 hours.
Pour chilled tea mixture into a punch bowl or pitcher. Stir in ginger ale and club soda just before serving.
To make simple syrup:
Bring sugar and water to a boil in a medium saucepan over medium-high heat. Boil, stirring occasionally, 4 minutes or until sugar is dissolved and mixture is clear. Cool to room temperature (about 30 minutes).
