1909 Mexican Peso -- Cleaned?

It's difficult to tell, due to the coin being photographed through a 2x2, but from what I can see I'm leaning heavily towards this coin having been cleaned or over-dipped.

This guy is one of my favorite sellers on ebay for all the diversity and general high-quality of his stock, but my biggest gripe is that so little effort is put into proper photography on his listings (often not even photographing both sides of a coin), and obviously cleaned coins are sometimes advertised as UNC or BU. So if there's any doubt in my mind whether a coin is cleaned or not, I always err on the side of caution and pass.
