How Much Do All BOSS DRAGONS Cost In Dragon Mania Legends? (Very Important Dragons Codex Page!)

So for no reason in particular, I wanted to go ahead and see how much it would cost to purchase all the boss dragons to complete the 'Important Dragons' codex page. Then of course, I was interested to find out the total cost of ALL boss dragons. Perhaps some of you will be interested to find out too!
