Rumors aren't super valuable, and your premise about the speed booster is wrong.Knowledge of another prince of earth is worth more than the body. Either as a new circle mate* or as warning against a very dangerous foe.
*Exalted are so much more effective in general when there is enough of them to specialize. If we could have another reliable ally we can bring into dangerous situations that would be worth so much in action economy.

The hell doesn't replace it because we don't have actual mechanics for that, and they can't provide exalted crafting anyway.
I want training instead because it's more valuable but there's a lot a value to be had in the available options.
The rumor doesn't seem worth nearly as much to me. The guy isn't going to betray Odin in his own workshop, so it's not going to be critical secrets.
Cursory side information about an effort Odin's running that this guy isn't even part of isn't worth trading away useful recipes and our second most valuable piece of loot.
Once we have the crafting charm those remains are basically the core components the exalted crafting system works with. The meat of our ability to step outside mortal crafting will be gated behind our supply of trophies like this.
