Scott Joplin pieces possibly leading to riches (4)
I believe the answer is:
rags
'scott joplin pieces' is the definition.
(I've seen this in another clue)
I can't explain the rest of the clue.
Can you help me to learn more?
(Other definitions for rags that I've seen before include "Tattered cloths" , "Tattered clothes" , "Waste scraps of cloth" , "Small pieces of cloth (but can be glad)" , "Pieces of old cloth" .)
