$15 is a numeric annotation glyph (NAG) for the symbol =/- or slightly better for Black. Anything with a $ followed by a number 0-255 can be printed out as a symbol.
A table of all the NAGS are here

Thank you very much!
I see:

1 good move (traditional "!")
2 poor move (traditional "?")
3 very good move (traditional "!!")
4 very poor move (traditional "??")

6 questionable move (traditional "?!")
7 forced move (all others lose quickly)
8 singular move (no reasonable alternatives)
9 worst move

11 equal chances, quiet position
12 equal chances, active position
13 unclear position

20 White has a crushing advantage (Black should resign)

Very interesting, first time I hear about!
Hi,
I posted this on the general discussion and did not hear an answer. I thought I would try here as well.
When I use the chess.com chess analysis I see a line that looks like this:
"({INACCURACY (-0.33)} 6. f4 O-O 7. Ngf3 c5 8. dxc5 Bxc5 9. Nb3 Ba4 10. Qd2 Nbd7 11. Nxc5 Nxc5 $15)"
Could someone please explain to me what the $15 means?
If this is explained somewhere on the chess.com website, I would appreciate it if someone could point me to that location.
Thanks!
