Morphology
The noun combines a specific type label 'pyx' (a mint box for coins awaiting assay) with the general container 'chest', so its meaning — a chest used for pyx/coins — is directly derivable from the constituents. Although 'pyx' is specialized vocabulary, for a learner who already knows both words the composition is fully compositional and predictable.
Etymology
Pyx chest comes from old mint practice: a small locked chest, the pyx, held newly made coins until they were 'checked' for quality. So it means a box used to keep coins safe at the mint until they are 'checked'.
