Graded Anacs

did the u.s. mint make a special strike on the 2009 high relief double eagle other than the business strike?

I had my 2009 double eagle gold coin graded by anacs and it came back as a SP grade? Or a satin proof or specimen proof? The mint does not admit to any special strikes just the standard business strike as in the brochure. Has anyone heard of a SP grading in relation to the 2009 double eagle? I have seen the SP grading on other coins and this is very confusing to me? Please explain if you know about this issue.

Could this be it?
