Gold
Karat, fineness, troy weight, melt value and the difference between a benchmark and a buyer's offer.
Explore gold →Price knowledge without the mystery
Know what metal is worth.
Understand the quoted market price, calculate contained-metal value, and compare a real offer without confusing spot, melt, scrap and retail prices.
Five starting markets
Learn each metal on its own terms
Precious metals are commonly quoted per troy ounce. Copper is commonly discussed per pound or metric tonne. The distinction matters.
Silver
Sterling, coin silver, bullion, flatware and the premiums or deductions that change a sale price.
Explore silver →Copper
Exchange benchmarks, pounds versus tonnes, cathode and the practical economics of scrap grades.
Explore copper →Platinum
Investment bars, jewelry fineness and why a smaller retail market can create wider spreads.
Explore platinum →Palladium
Industrial demand, jewelry purity and the care needed when estimating recoverable metal value.
Explore palladium →From quote to cash value
One number is never the whole price
A useful valuation separates the market reference from the material inside an item and the costs of completing a real transaction.
Reference price
Identify the instrument, source, currency, unit, timestamp and whether the number is bid, ask, midpoint, fixing or futures.
Contained metal
Convert gross weight into fine-metal weight using karat, fineness, assay or a defensible recovery estimate.
Melt or benchmark value
Multiply fine-metal quantity by the comparable unit price while preserving the calculation so it can be checked.
Real transaction
Account for premiums, refining, contamination, testing, shipping, inventory risk, dealer margin and collectible value.
Useful without a data feed
Bring a price. Check the mathematics.
Each calculator accepts the published reference price you choose and shows its formula instead of hiding assumptions behind a single result.

Markets make more sense in context
Four cited long-form papers trace how weights, assay, coinage, mints, merchant networks, refineries and exchanges made metals saleable.

Source, unit, time and market basis
A number labeled only “metal price” is incomplete. All Metal Prices is being built around a stricter rule: identify what is priced, where, in which unit and currency, at what time, from which source, and whether that value is actually available to a retail seller.
