It depends.
If its like this:
4th Gen Timid Shiny Latios
Levitate
Flawless Hidden Power 70 Fire IVS
Heal Ball
One with an undecided Nickname, two with its default name (LATIOS/Latios).
Semi-Redistribution Rights
Then it would be worth about 3 credits to me. I normally trade the Jirachi for around 6 credits or so.
