Material values were taken from the Guild Wars 2 Wiki and simply multiplied by 250:
Powerful Blood = 10,682.5 silver
Powerful Venom Sac =1,560 silver
Elaborate Totem = 5,742.5 silver
Pile of Crystalline Dust = 5,370 silver
Vicious Fang = 6,327.5 silver
Armored Scale = 6,000 silver
Vicious Claw = 6,152.5 silver
Ancient Bone = 6,760 silver
Glob of Ectoplasm = 9,375 silver
Since 100s = 1g we can simply divide the sum of all this by 100 for the gold needed.
After adding all that up and dividing by 100 I came to the figure 579.7 so the gift of fortune alone is way expensive, and this doesn’t even count the mystic clovers either but that requires luck but in a best case scenario:
77 Ectos = 28.8 gold
77 Mystic Coins =20.79 gold. However, since there’s a 33% chance at a clover we can triple these figures since a third of 100% is 33.333…%:
86.4 gold for the ectos and 62.37 gold for the coins.
So we can conclude that a gift of fortune cost if we were to buy every single part would be like 728.47 gold. This sounds like quite a big deal but you need to understand that if you’re playing the game naturally you’d likely have lots of free ectos lying around from salvaging rares gained from Silverwaste, Tequatl, and Heart of Thorns zones.
