The term COLLECTOR'S GOAL can be broken down into two crossword solutions: SET (3 letters) and COMPLETES (9 letters). A collector's goal is to acquire a complete SET of items, such as coins, stamps, or trading cards. This could involve collecting all the items in a series, or all the items from a certain manufacturer or time period. Collectors often strive to find rare or hard-to-find items to complete their sets.
