Our mission
AllMetalPrices.com is an independent educational publishing project about metal markets and physical-metal value. Our goal is to answer the practical questions hidden behind a price quote: What unit is this? What purity does it describe? How much fine metal is in an object? Why is a retail price above spot or a scrap offer below it?
We build resources for people comparing an inherited item, learning about bullion, sorting scrap, studying commodity markets or exploring how metals shaped trade. The site is useful only when assumptions remain visible, so our tools show their inputs and our guides explain their limits.
What we publish
Metal value calculators
Manual-input calculators for contained gold, silver, copper, platinum and palladium value, plus weight conversion.
Explore calculators →Practical explanations

Focused pages that connect each metal's quote convention, forms, uses, value tool and further reading.
Browse metals →Market history
Long-form, cited studies of gold, silver, copper and the development of precious-metals trading.
Open the research library →Why prices are manually entered
The first version of the site is intentionally static. It does not fetch a market-data API, show an unlabeled delayed feed or suggest that an old number is live. Visitors bring a current reference price from a source they trust; the browser then performs the conversion privately.
This makes the tools fast, inspectable and resilient while keeping the distinction between market data and calculation clear. If live data is added in the future, it must carry a source, currency, price basis, timestamp and delay status.
Our standards
- Show the basis. Units, purity and formulas should be visible.
- Label uncertainty. An estimate is not an assay, appraisal or guaranteed bid.
- Protect context. An intact object may have collectible, historic, artistic or gemstone value beyond metal.
- Prefer evidence. Research should cite primary or authoritative sources where they are available.
- Correct the record. Specific, well-supported correction reports are welcome.
- Protect calculator inputs. Calculator entries are processed in the browser and are not sent to All Metal Prices.
What we are not
All Metal Prices is not a metals exchange, benchmark administrator, mint, refiner, dealer, broker, investment adviser, assay laboratory or appraisal service. We do not buy metal and do not provide personalized financial, legal, tax or appraisal advice. Commercial relationships, if introduced, should be disclosed where they could affect a reader's interpretation.
Start with your question
- What does spot price mean?
- How much gold is in this item?
- What is sterling silver's melt value?
- How do I value copper by the pound?
- Why does bullion cost over spot?
- How did metal trading develop?
Contact and accountability
At launch, All Metal Prices is an independent educational publishing project, not a named advisory firm or credentialed review panel. This edition does not list individual author or reviewer biographies, a legal-operator profile or a physical business address because those details have not been established for publication. Readers should assess a page through its visible inputs, source trail and correction record—not an implied personal credential.
The Research Desk page explains exactly what the organizational byline means and how a release is produced. Read the editorial policy and calculation methodology, report a problem through Corrections, or reach the project through the contact page.
