Unprized → It is formed from "un-" (meaning not) and "prized" (from the root "prize" which comes from Old French *pris*, meaning value or worth). The word "unprized" means not valued or not considered worthy.
Think of 'not' ('un-') valuing something ('prized') — that's why unprized means something that is not valued.
