You have to consider that when CRS started, A grade was pretty good already as B, and C grades being lesser. Then some tiger tooth and V came out, they look better than A (or, should we say they were harder to get than A), so they have to give it a new class. Since no alphabet is before A, the grade "S" came out (likely means super or supreme). And a few years later, even nicer pattern came out such as hinomaru or no entry, they couldn't just give it grade R (before S) because it would be confusing, so the term SS came out. SSS is the same thing. Nowadays you even hear SSSS or SSSS+ being used.
Ten years ago, a S grade tiger tooth was worth a lot more than the regular SSS you can buy today. And in Asian market, you'll find that most of the time SS sell for a higher price than SSS because most, if not all SSS have some golden gene in it, so the colour just isn't as good. However, in this hobby things keep changing/advancing. Nothing is impossible, SSS with very nice colour are not as rare as they were a year ago.
