However, the gold price disparity between Felen and Earth is significant.
In Felen, gold is relatively cheaper because it is easier to mine and there are more sources.
Don't view Felen's mining level with the public eye, but with the eyes of the spellcasters.
Even places like Colossus City with their automated mining lines are not the top tier.
The most advanced method is multiverse trade, directly selling or mining gold in the Earth Elemental Plane, where the gold extracted is often shockingly pure, not needing any refinement.
The same goes for other metals.
The reason for adopting the gold standard is because of gold's multi-purpose use, which keeps its price relatively stable—the sources are broad, and the consumption is great; many spellcasting materials for spellcasters can directly use gold, which gets consumed and burnt when used.
