I have a letter signed by JFK on White House stationary. From the best of my knowledge it seems authentic. I can't find any secretarials that match it and its very smooth and flowing. Its one of his "messier" autos. Anyways the problem is that it was laminated by a moron and there is no way to undo the lamination. I was wondering on a value for this as I know it would be decreased since it is laminated. Also if I send it to PSA or JSA will they even authenticate lt since its laminated....any help would be much appreciated!!
