Morphology
The compound is compositionally a 'sign' related to 'pound', so a learner who knows both words will infer it denotes a symbol for something called "pound". However, the conventional target symbol varies by dialect/use (many speakers expect '£' for the currency while American usage often calls '#' the "pound sign"), so the specific reference to the hash/number symbol is a culturally-specific naming convention and not reliably predictable from the parts alone.
Etymology
Pound sign # grew from a quick way to write the weight 'pound' long ago, when writers shortened 'pound' into a crossed mark that became #. Phone makers later called that mark the 'pound sign', so in American English pound sign now names # used for 'numbers' and tags.
