The lines outside the memorial concern me...but the lines inside the bays do look strikingly like the 1994 doubled die reverse that really started this whole subject. An overlay of those lines (on the 1994) do match up exactly with the fluting lines on the columns, so that's the first step with this coin. These are either fluting line doubling, which would be big, or they are well placed gouges of some sort that continue with the (almost certainly) gouges on the outside of the memorial building.
