I think this is neither PSD nor a greased die. There are no scratches as one would expect with a PSD and the erased part of the "1" meets sharply with the non erased part (abrupt change) making it less likely (in my mind) to be a grease filling, as it would have spread evenly. The "1" is an incuse device in the working die, so no die chip there could have filled it. It looks like 2/3 of the "1" in 1977 were missing in the hub die, due to a die chip on it. Is that possible? What could have filled that part of the "1" in the working die?
Thanks,
Adrian
