Is my Coastal really a coastal?

Here is 2 pics of my carpet. It was sold to me for only $75 as a coastal, but after seeing not many coastals on here and seeing how close they compare to other carpets i figured id get your opinions and double check she is a coastal. Either way she still a beauty, very tame,and awesome.

The various carpets have been mixed and matched quite a bit over the years; and I rarely come out and say YES or NO in these situations (because I don't feel identification should be based on what somebody thinks it looks like...which is too often how it happens). Here's the problem - some people would breed a pure coastal with a nice looking variegata (or a not so nice looking jungle, lol), and call the babies coastals.
For me, if the lines can't be verified, I am pretty hard pressed to consider any carpet pure anything.
