Patriarch Phil Robertson personally tested and signed the call at the Duck Commander store in Louisiana, to crowds of fans.
Some traveled all the way from Oklahoma to see the special event.
Proceeds from the auction will go top support the Northeast Louisiana Veterans Association's Wounded Warriors.
Phil Robertson says, "For our sons and our daughters to go forth and give their life, their arms, and their legs for that cause, the least I can do is try to help them out."
The 1 millionth duck call was designed after Robertson's original wooden call. You can find out how to big on the call on their website here...
