Comparison · MyCoinage vs Numista

Numista catalogues.
MyCoinage values.

Numista is the best free numismatic catalogue on the web. MyCoinage is built for valuation, realised auction prices, grade-by-grade history and portfolio tracking, with a UK and US focus. Most serious collectors use both. Here is the honest side-by-side.

The short version Numista is a community-built encyclopedia of every coin ever minted, with hundreds of thousands of entries and a worldwide editor base. MyCoinage is a UK and US focused valuation platform: realised auction sales from Spink, Baldwin’s, Noonans and verified eBay sold listings, aggregated by grade, plotted as price history, with a portfolio that revalues itself daily. They solve different problems. This page is not a takedown of Numista; it is a guide to which tool fits which job.

Side-by-side comparison

Marked fairly. Where Numista does something well, it gets a tick. Where the answer is "kind of", it gets a partial mark.

When to use which

Use Numista when

You are identifying a foreign coin, researching a variant from a country MyCoinage does not cover deeply, browsing the world’s coinage by region or ruler, or trading duplicates with collectors abroad. Numista’s catalogue depth and community are unmatched.

Use MyCoinage when

You want to know what a UK or US coin is actually selling for today, in a specific grade, based on real auction hammer prices. You want a portfolio that revalues itself, a price chart per coin, and PDF insurance exports. You want editorial pricing guides written in British English by a named editor.

Use both when

Honestly, most collectors do. Numista is the reference shelf; MyCoinage is the valuation desk. Identify a coin on Numista, then track its market value and your portfolio on MyCoinage. The two sites are complementary, not competitive.

What MyCoinage adds on top

Four things Numista does not currently set out to do, all built around real market data rather than catalogue values.

💵
Realised auction prices
Hammer prices only. No asking prices, no active listings, no estimates. If a coin sold at auction, the figure goes in; if it did not, it does not appear.
📈
Grade-by-grade history
Every coin page splits prices by grade (Fine, Very Fine, Extremely Fine, About Uncirculated, Mint State) so a VF and a MS65 are never lumped together.
📊
Portfolio value chart
Your collection’s total value is revalued daily and plotted over time, so you can see whether your sovereigns or your 50p set are actually appreciating.
💰
UK auction sources
Hammer prices from Spink, Baldwin’s, Noonans and verified eBay UK sold listings, plus US data from PCGS-supported sales. Sources are cited on every coin page.

Is Numista a competitor?

Not really. Numista is a free, volunteer-built world catalogue. It is the place to identify a coin and read about its history. MyCoinage is a focused valuation tool for two markets we know well, and a tracker for the collection in your safe or your album. We link to Numista in our own editorial guides where it is the better reference, and we will keep doing so. If you collect world coinage broadly, you should be on Numista. If you collect British or American coins and you care about market values, MyCoinage will tell you things Numista cannot.

One honest caveat. Numista’s premium tier removes ads and adds storage; ours unlocks Pro features (full price graphs, PDF export, alerts, unlimited coins). Different tiers, different jobs. Our pricing page lays it out in full.
