Rewards are fixed for platform for particular day, and nobody knows what they are except IGG or someone who bought them, made screenshots or wrote what he got and posted them.
Coffers are $1, $2, $5, $10, $20, $50. I presume there is also $100, but I never went that high. Out of the ones I got, I haven't seen any dragons, although I think Lavanica bag was in one of them. Not sure. Either way, each time the loot is different, so it is possible that a day when I didn't get coffers there was a dragon. Unlikely, but possible.
While Fe203 is completely accurate in that "nobody knows what they are expect IGG or someone who bought them", I will go out on a limb and tell you not to expect to see a dragon in this offer. Maybe a few soulstones, but not a dragon.
there'll be dragons there from time to time..but it'll be Molt or Arc, and eventually demo, and one day skelly
