Thousands of pesos — "diez lucas" is ten thousand.
Colombian prices are large numbers, so people drop the thousands. "Treinta lucas" is 30,000 pesos. Common in Bogotá and among younger speakers everywhere. "Plata" is the general word for money.
Chile uses "luca" the same way for 1,000 pesos. Mexico says "varo," Argentina says "luca" for 1,000 too.
Reading a definition isn't the same as saying it to someone. Lingo Kaiava is a voice tutor set to Colombian Spanish — it uses lucas the way locals do, corrects you in the moment, and never "fixes" the way real people actually talk into textbook Colombian Spanish.
