What ㌣ means
No. It spells セント (“cent”); 銭 is the Japanese sen unit.
Japan introduced sen as one-hundredth of a yen in 1871 and ended sub-yen currency in 1953. ㌣ uses the borrowed English currency word “cent.”
Why does ㌣ become セント?
The square is typographic; セント is the word.
Compatibility normalization, a text-cleanup rule, maps ㌣ to セント, so software applying it can drop the square. ¢ is the ordinary cent sign.
A compact form from Japanese typography, not a conversational signal.
Read セント as “cent”; 銭 names Japan’s old sen unit.
