About CoinData

Our Purpose

CoinData.ca brings Canadian coin identification, varieties, rarity information and market research together in one accessible reference. It is designed for serious numismatic researchers and collectors at every level, from those identifying a single coin to enthusiasts comparing varieties and historical sales.

Our aim is to make useful Canadian coin information easier to explore, compare and understand while continuing to expand the underlying reference records.

More Than 10,000 Recent Sales Tracked

CoinData tracks more than 10,000 recent Canadian coin sales, and that collection continues to grow. Recorded auction results provide a practical basis for researching realized market prices across denominations, dates, varieties and grades.

Where available, the Coin Values tools help visitors compare recorded sales with catalog information. A realized sale is a historical transaction, not a guarantee of the price another coin will achieve.

Market comparisons require context. The date of sale, assigned grade, certification, variety attribution and the number of comparable transactions can all influence how useful an individual result is. CoinData distinguishes recorded sale prices from catalog values and precious-metal melt values so that visitors can consider different kinds of valuation evidence rather than treating them as interchangeable.

Canadian Coin Research and Classification

Beyond sale prices, CoinData brings together varieties, errors, mintages, specifications and rarity information. Its CoinData Reference Numbers (CRN) help identify and connect particular coins and varieties across the reference and sales databases.

Visitors can use the Rarity Database to browse reference information, or Explore & Search to locate records by denomination, year, variety and other identifying details.

Consistent identification is essential when comparing coins that may share a date and denomination but differ in design details or recognized varieties. CRN identifiers provide a way to connect related research records; they are CoinData reference identifiers, not a substitute for professional grading or third-party certification. Rarity descriptions should be considered alongside the available historical and numismatic evidence.

Practical Tools for Collectors

CoinData also provides denomination galleries featuring coin varieties and errors, along with a Precious Metal Melt Value Calculator for eligible Canadian coins. These resources complement the sales and rarity databases by helping collectors research both collectible and metal-related values.

Our Articles and Gallery provide additional ways to explore Canadian numismatics.

Specialized Numismatic Research

Beyond coin valuations and rarity classifications, CoinData provides specialized research resources covering Canadian mint errors, die varieties, die rotations and specimen provenance.

Our photographic galleries document identifiable varieties, design differences and minting anomalies, helping collectors compare specimens and recognize distinguishing characteristics. Rotation and major-error records provide further context for unusual minting outcomes, with associated sales information where available.

Provenance records help researchers follow individual specimens through documented auction appearances, supporting comparisons of identification, certification and market history. Together, these resources contribute to a more complete picture of Canadian numismatics.

A Dynamic Canadian Coin Market Reference

Printed catalogues and static price guides remain useful historical references, but market prices can change between editions. CoinData provides an evolving view of Canadian coin sales as additional verified auction results are incorporated.

With more than 10,000 tracked sales and a steadily expanding database, CoinData's Top 10 Highest Prices Realized feature highlights notable sales from the preceding six months. Recent-sale records offer additional context for actual market activity.

The Coin Values database distinguishes realized prices, historical sales, catalog reference values and precious-metal melt values. As new sales are recorded, market statistics can evolve while older transactions remain useful historical evidence. These are dynamic, evidence-based comparisons—not guarantees of future selling prices or claims of real-time valuations.

An Evolving Reference

CoinData is an actively developing research resource. As additional sales and reference material are recorded, its databases continue to expand, supporting comparisons across an increasing range of Canadian coins.

Questions, corrections and research inquiries are welcome through our Reach Us page. We value careful identification and source-based information as the reference develops.

Maintaining a useful reference involves more than adding records. Clear variety attributions, accurate grades and faithful reporting of source information matter when historical sales are used for research. CoinData aims to make its information practical to evaluate, while recognizing that auction descriptions, identifications and market conditions can differ. Visitors are encouraged to review individual records critically and report possible errors or omissions.
