Aaron M.Mike, you are officially on pennant authentication probation. 
I'm not so sure the seller wouldn't have been better off selling them on E-Bay. (Hopefully the seller consigned the pennants to Hunts rather than selling them outright to Hunts.)
The White Sox pennant is unique but unremarkable unless it specifically dates to 1917-1919 -- and even then it's rather bland. I would think it would sell in the neighborhood of $1,200 or so.
The Tigers pennant is nicer (although not one of my favorites), but I've seen it offered a few times before. I would price it about the same.
But at least now you know they are both authentic, and where and when they will be made available for sale.
