I'm at the end of the game, the Sky Fortress Bahamut appeared, and I decided to go after some of the ultimate equipment (mainly the Tournesol and Masamune) and the rest of the Marks. I have been doing alright with the loot collecting for the Tournesol until I found out how much the Canopic Jar (to get the High Arcanas) was. 250,000 Gil, I only have over 222,000 Gil now. I have been having Gil problems all throughout the game and it took me a long time to get to this amount. 
Seeing that, with how much the Tournesol is (600,000) and the Masamune (350,000): Where is the best place to get loot that sells for a lot of Gil?

I beat Zeromus (which was pretty challenging for me, at level 67.), and got to that area. I found out that 99 Blood-darkened Bones sell for 142,065 Gil. That means I'd have to do that around 10 times to get the Gil needed for the Tournesol and Masamune. Not too bad actually, doesn't take too long for me to 99 of them.
