Thinking might have found double lobe 88? Can someone else give opinion or please verify. Also it looks like the second 8 is over a 4
I think the ear took a hit, if you could please, take a image of the doubling you see on the date . Pretty please ....
The lobe is pretty normal for the year, the date would be interesting to see, That could be a die chip or plating bubble under by the 8.
I am looking at the triangle point between the two 8's. If the op could post a couple close ups that would be great.
