I've never seen that before. If that's supposed to be a minus sign with the 10, then it would be a flatted tenth. I would notate THAT as a #9.

It's possibly shorthand for roll the tenth. The old Stride pianists used to do this.

Wiki wrote: The pianist's left hand may play a four-beat pulse with a bass note or tenth interval on the first and third beats, and a chord on the second and fourth beats

Sorry, it was not a question. It is a C7#9 chord. I should have mention that to avoid the confusion

I don't believe it's easy to find this notation (edit:c7-10) today unless you know some older jazz cat.

On thing with 7ths and what one you are using often depends upon the style of music you are playing. Rock and most blues use mainly the 7th called 7th or a half step down from the M7. Old standards and jazz use the M7 a lot some pop and rock dose. Jazz will often use all kinds of 7ths in the same song.
The c7#9 is used a lot often as the V Chord in some blues.

remember, too, that that kind of seventh is (traditionally) determined by key. In the blues this isn't always true (since it's not atypical to only use Mm7 chords) but in more conventional pop and rock music if you see many different "kinds" of 7ths it's usually related to scale degree; IM7, iim7, iiim7, IVM7, V7, vim7, viim7b5 (aka half-diminished 7th, I didn't feel like opening the character map).

Then of course there are secondary function chords (a I7, for instance, functions like a V7/IV) which appear too.
