The possibility of it being fake is slim, with those kind of marks it is more likely poor quality control and a simple case of toning happening in the scratch/dent area.

Failing that, crack it out of it's assay card and do a specific gravity test on it, that will give you a very good indication of how real it is.
For example, the FED needs to get on this and keep yields low for as long as possible, more QE will be needed and for sure is coming;
The difference today to yesterdays QE is the government will be the ones spending it, indirectly into materials and energy for massive infrastructure projects, like for example in the UK, windfarms to power the entire country, 200 billion into infrastructure spending, that kind of thing. Inflationary. Multiply that across all western nations who will be competing with developing eastern nations (India, China, etc). Eventually the FED will have to let rates rise to follow the inflation that will result, they said that is the plan many times. The BoE has most of its pension funds, I think it was 90% of it in index linked investments, that should tell you what is coming more than anything they say. That is not good for the consumer and cheap borrowing (housing).
