Mint bars? (6)
I believe the answer is:
ingots
'bars?' is the definition.
(I've seen this before)
I don't understand how the rest of the clue works.
Can you help me to learn more?
(Other definitions for ingots that I've seen before include "Bars, of gold say" , "Brick-shaped blocks of metal" , "Metal bars" , "Lumps of metal, say gold" .)
