Do Old Credit Cards Have Any Value?

They do have some value, If you reserve them for memory or for collection.
Some of the cards may be the special one you gained at special time,so it is worth being treasured up . Some may have good appearance,as the banks often issue beautiful cards to attrack people's eyes,so you can collect them as a fun,just as we collect match mark and sweat paper.
In general, I treasure all things I have used or owned, they accompany with me, and become part of me.
