I have two Dr pepper bottles from 1923. I would like to know the value of them. Thanks

A cursory check on Ebay for vintage Dr Pepper soda bottles (http://www.ebay.com/sch/i.html?_nkw=dr+pepper+bottle) shows that vintage bottles can go anywhere from a few dollars up to hundreds, depending on the type of bottle and whether there is any unique quality to them, like special commemorative designs, etc.
