New York garbage collector spots 100 leather jackets (8)

'new york garbage collector' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'spots 100 leather jackets' is the wordplay.
I cannot quite see how this works, but
'spots' could be 'rash' (I've seen this before) and 'rash' is found in the answer.
'100' could be 'c' (Roman numeral) and 'c' is located in the answer.
'leather' could be 'tan' (tan can mean to convert into leather) and 'tan' is present in the remaining letters.
This accounts for all the letters.
This may be the basis of the clue (or it may be nonsense).

Can you help me to learn more?
