Gettysburg Address Lincoln 1863 Aluminum Collectible

When I found this item at the bottom of an auction box from the estate of a very old woman, I was excited as it has engraved on the top: Gettysburg 1863. It has all the bumps ad bruises that it could be of that era, but not according to the expert appraiser at the Antiques Roadshow. That person thinks it is old, perhaps in the early half of the 1900s and suggested that it could have been a commemorative souvenier from Gettysburg Pennsylvania of Lincoln's famous speech. This container of 5 (about 3 oz.) drinking vessels made of aluminum is 3 1/2 inches tall and at its widest point, it is 2 inches in diameter. The appraiser estimated a value much higher than my starting bid; but I will let the auction process determine the value.
