Latin Abbreviation?

While studying Lingua Latina Capitulum VIII last weekend, I noticed a certain abbreviation used in Pensvm A reading, HS.C. I wondered what it meant, but more why it was abbreviated in the first place. Does anybody know why those words were not just typed into the text? Thanks!

Yes i was also wondering about the abrivations in the Lingua Latina.

Salvete.

Without the context, I may be wrong, but I believe that HS. is the standard abbreviation for ‘sestertium’, or sesterces, the unit of currency. C (centum) is the Roman numeral.

Valete.
