In my hometown of Windy, I received 602 gil from this card from npc. My fame is decent. AH price is 5k (don't know why) but rarely sells. One was listed and was not selling so I choose npc!
From multiple posts that I have seen around the site, that is a false rumor. From what I have found, only two of these cards have any worth, and those are for a quest. This card is not one of them.
