Well. One thing I see is the familiar brillo pad cleaning marks. I have Nikkor 50/1.4 with an objective that was seriously scrubbed with a scout pad and a generous helping of fine beach sand.
The other weird thing I see above appears to be coating damage. I have seen it before a couple of times...once on a UV/IR filter, another time on a rollei lens that had Pepsi splattered on it. The soda somehow damaged the coating. The lens above looks like the soda was inside the lens!
