In "Shelling Out — The Origins of Money," Nick Szabo catalogs historical collectible monies whose value depended on the cost of producing them, and traces what happens once that cost falls. Venetian glass beads are captioned in his account *"When costliness becomes forgeable"* — once glassmaking technology made beads cheap to mass-produce, their monetary role collapsed. Wampum tells the same story with a number attached: its value was *"inflated one hundred fold by Western harvesting and manufacturing techniques"* before wampum, like gold and silver jewelry before it, was demonetized.

The mechanism is general, not specific to shells or glass: a collectible or metal functions as money only as long as its scarcity is expensive to replicate. Once a production technology cheapens that replication, the costliness premium — and with it the monetary role — collapses. Szabo uses this history to motivate bit gold's opposite design goal: see [[claim-szabo-bit-gold-grounds-value-in-unforgeable-cost-of-production]].

This is the same collapse shape later modeled, independently and in a different domain, for asteroid-mined platinum-group metals in [[claim-asteroid-pgm-price-holds-then-collapses]] — a precious metal's price falling toward a new, much lower cost of production once a cheaper extraction method displaces the old one. See [[observation-unforgeable-costliness-bridges-asteroid-pgm-and-bit-gold]] for the connecting synthesis. Separately, the vault also holds a real-world test of whether historical production-cost collapses actually follow this "hold, then collapse" shape or instead fall continuously — see [[claim-cheaper-extraction-disruptions-fall-monotonically-not-hold-then-collapse]], which finds the latter for aluminium and AI inference. Szabo's own wampum and glass-bead cases describe the *fact* of collapse, not its trajectory, so the two claims are complementary rather than in tension.

> [!note] Seek's commentary:
> The wampum "hundredfold" figure is a quantitative claim, and the sourcing floor requires Tier 1–2 for those — Szabo's own essay, at Tier 2, clears that floor on its face, so I haven't flagged it `[unverified-quant]`. But I did not independently re-fetch the essay this session to confirm the figure verbatim, so treat the number with the same light caution as any capture-sourced quote pending a primary re-read. — Seek
