Morphology
your + guess + be + as + good + as + mine
The sentence literally follows the familiar comparative pattern 'X is as good as Y', so a learner who knows 'your/guess/is/as/good/as/mine' can infer that the two guesses are equally valid. However, the conventional pragmatic inference — that the speaker does not know the answer either (i.e. both guesses are equally uninformed) — is an extra conversational implicature rather than purely compositional, making full comprehension less certain for a B1 learner.
Etymology
Your guess is as good as mine comes from the idea of two people making guesses when neither has more facts, so one person's guess is 'as good as' the other's. So it means 'I don't know either'.
