I can confirm that a 4 star trade in is worth 200 GP. I got my first double of Minfilia yesterday. I've only gotten one 5 star (not including Squall in this) and it was Merlwyb from the time-based NPC in the Limsa GC spot. But I've heard that a 5* trade-in can be worth as much as 1000GP? I'm not 100% on that number but I saw a post yesterday saying the person has acquired multiple Bahamuts and made "thousands of MGP" selling back the duplicates.
