FF1, that is an impressive collection of CW saved History. Very Well done. Maryland and Virginia both still have great amounts of relics being found. The only two U.S.box plates I have in my collection were sent to me by one of my older cousins who lived in Alexandria,Virginia. One was found in the Chancellorsville battlefield area, and the other from the Harper's Ferry aerea. These were most appreciated. I have seen 4 dug through the years, but I have yet to find one myself.
