They are in pretty bad shape, but having said that, are the prongs intact on both buckles? It looks like they are. If I had to guess and I'm not a Civil War dealer, but if they're authentic I would put a value on them of somewhere in the $40 to $80 range.Pristine Union buckles w/prongs intact, are going somewhere around $250 to $300 range....Still a very cool piece of history!
