supply
供給 — Phenomena
The quantity that comes onto the market.
Silver denier of Pippin IIIc. 755

Wampum (belt of shell beads)17th century (the age of trade money)
If a silver mine is discovered, the supply of silver increases, and as it increases, the value of silver falls. ⚠ As long as currency itself is also a commodity, it cannot escape this logic.
