✕Common Mistakes
Un libro es 20 sellos.
Use 'tener' for possession; 'es' (ser) describes identity, not ownership.
Un libro hay 20 sellos.
While 'hay' can be correct, it changes the focus to existence; if you want to stress possession, keep 'tiene'.
Un libro tiene veinte sello.

Cultural Tip
In Spanish‑speaking countries, 'tener' is the default verb for possession, while 'haber' is used for existence. Saying 'Hay veinte sellos en el libro' focuses on the existence of the stamps, whereas 'tiene' emphasizes that the book possesses them. Also, stamp collecting (filatelia) is a popular hobby, so this sentence might appear in a conversation about a collector's album.
