Gold & BeaverCoin

Two currencies drive the village: Gold (common โ€” the building currency) and BeaverCoin (rare โ€” a prestige currency).

This ladder applies to expandable buildings (housing + extraction) โ€” the BeaverCoin + Gold cost is the same whichever you expand. Production stations don't use it (they upgrade by tier, paying their own per-building cost), and fixed- or step-limited buildings don't expand at all.
