There is some ongoing debates across the web pertaining to whether black back normals and high gold normals are simply a "morph" on it's own, plain old genetics/traits, simply a result of random breeding and so forth.
That being said, here is some references via Ralph Davis Reptiles (reputable breeder) as to what you should be looking for in "high golds" as well as "black backs":
http://www.ralphdavisreptiles.com/collection/pythons/ball/high_gold_ball_python.asp ....in which the gold in a normal ball python is more prominent than the other normals, making it lighter, and considered the "prettiest" of the normals
http://www.ralphdavisreptiles.com/collection/pythons/ball/black_backed_ball_python.asp ...simply a solid black pattern running across the snakes dorsals...just as pretty
Also note that the "normal" wild caught ball python has a wide array of patterns, levels of darkness in color as well as lightness namely amounts of gold, brown, black, orange, etc resulting in animals that stick out from the rest, etc. leading to the beginning of ball python breeding, selective breeding (breeding specific visual traits to one another in hopes of making more of a desired trait)
It would help if you knew who fathered the clutch, the sire and what his traits were.
Visually, your snake looks like a normal but pretty normal nonetheless. The amounts of black on your baby looks really nice.
You can always try breeding it later down the line to other Ball pythons with other amazing visual traits or same traits and see what pops up (proving out traits through breeding)
All I gotta say is pretty snake and have fun girl!
