Michael,
I am sorry to say that those flags are identical in construction to the "decorative reproductions" that were listed as authentic relics on eBay in the 2003-2006 time span. The Northern Virginia Relic Hunter's Association waged quite a battle with eBay to get those pulled, or at least listed under "Reenactment / Repro." Their retail value as decorative items is in the $200 to $400 range, but they still come up at some "brick and mortar" auction houses as authentic ACW or Veteran items.

The link below is to my Flickr photos of Veterans' flags and ribbons, mostly Union, dating from the 1880's to the early 20th C.
