Honestly if u buy photocards from official sites, or albums then ull know, bc when its from a normal album then its like a common photocard, if its from a special album, a signed album, or a special or signed photocard set, then it INSTINTLY becomes rare, sooo yeah, or if u get them as a paying member of some group, and you get sent a specific card set or album or smthn like that then thats also pretty rare
