Even if (as you say from your perch), I see only what's there for me to see, it's enough to see that you made an untrue assertion. Using the term "semi-prooflike" isn't necessarily about asking or charging extra money for a coin. I know, because I sometimes use that term in write-ups of coins we offer for sale. And in each and every case, the asking price has already been determined, before I write a single word.
Also, as I mentioned previously, some coins - such as rare business strikes that can be very difficult to distinguish from more common Proofs - are worth less (not more) if they exhibit semi-prooflike or proof-like surfaces.
