A closer show of the lower area below the base of the Memorial would help. But I think you have linear plating problem under the plating (AKA gas bubbles). In the early 80's these were very common and not a good thing to get on a variety. They distract the eye and I know it is something for me not to buy when I see them. But later on they got better about the problem which was a rinse issue with the zinc. But every now and then they still appear. The line from the left roof looks like one, but on the right roof and cornice, I don't know what is going on there?m If maybe coin contact if it is incuse on the field. They get interesting to see when they fall over the devices, but not worth anything extra. IMOHO
