Small-time? (6)
I believe this is a double definition.
'small' is the first definition.
(similar in meaning)
'time?' is the second definition.
(unit of time)
(Other definitions for minute that I've seen before include "Precise" , "Tiny; written note" , "barely noticeable?" , "Little -- 60 18 across" , "Tiny - proportion of time" .)
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">small-time</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is all the clue.<br/ ></span>
(Another definition for penny ante that I've seen is " small stakes".)
