Morphology

not + worth + a + brass + farthing

The meaning 'completely worthless' is directly derivable from the parts: 'not worth' (having no value) plus 'brass farthing' (a very small/cheap coin), so it literally means 'not worth even a tiny coin.' Although the phrase is somewhat archaic, the monetary-minimum-value logic is compositional and cross-linguistically familiar, so a B1 learner who knows the constituent words would understand it.

Etymology

Not worth a brass farthing may come from old British coins: a farthing was a very small coin and a brass farthing was even cheaper, so it had almost no value. That's why the phrase means 'completely worthless'.
