I believe the answer is:
<span class="explanation-format__ClueExplanation">'<span class="explanation-format__original">roman coins</span>' is the definition.<br/ ><span class="explanation-format__explanation">(I've seen this in another clue)</span><br/ ><br/ >This is the entire clue.<br/ ></span>
(Other definitions for denarii that I've seen before include "22 [COINS]" , "Bits" , "Ancient Roman coins" , "money from abroad" , "Silver coins of ancient Rome" .)
