Starting a coin collection is exciting. Whether you're drawn to historic UK coins, iconic US series, or the thrill of finding a rare date in your change, collecting quickly becomes more than a hobby. But as collections grow, so does the challenge of keeping everything organised, understanding real market value, and knowing what to collect next. That's where MyCoinage comes in.
MyCoinage is a UK-built platform designed for collectors who want a modern, structured way to manage their coins. Instead of spreadsheets, scattered notes, or memory, everything sits in one place: catalogue, valuations, portfolio tracking, completion tracking, and a community layer. Below is a practical tour of what the platform does today and where it's heading.
Live realised prices, not asking prices
The single most-important difference between MyCoinage and most "coin value" sites: we publish realised prices — what specimens actually sold for at auction or eBay completion — not dealer asking prices. Our scrapers pull verified sales from eBay UK, Spink, Baldwin's, London Coins, Coin Cabinet, Hosker & Haynes, NumisBids and Onebid — eight venues that together capture most of the UK numismatic market. The median, range and 30-day trend on every catalogue coin reflect the price the market will actually pay.
Asking prices and active eBay listings are filtered out at the data-pipeline level. If a dealer is asking £1,500 for a coin that auctions consistently at £800, the catalogue page shows you the £800 — and we publish the source data so you can see for yourself.
Track your collection like a portfolio
Add coins to your collection from any catalogue page in two clicks. Each entry holds the standard information — grade, purchase price, purchase date, source — plus optional photos, slabbing references, certificate numbers and notes. As market data updates, your collection's total value updates with it. The dashboard shows total acquired vs. current value, gain/loss in pounds and percentage, and per-coin breakdown so you can see at a glance which holdings are pulling weight and which aren't.
The portfolio chart (Pro feature) reconstructs your collection's value over time using realised-price history, giving you a stocks-and-shares-style growth chart for what was previously an opaque hobby. The free tier covers up to 25 coins, which is more than enough to get a feel for the platform; Pro at £2.99/month removes the cap and unlocks the full per-sale price-history graph and PDF insurance reports.
Series tracking and completion
The Olympic 50p, Beatrix Potter 50p, Mr Men £5, Music Legends £5 and the Britannia bullion £2 series are all in the database with full year-by-year coverage. Add a coin to your collection and its slot in the series checklist auto-fills; missing pieces stay highlighted so you know exactly what you're hunting for. The series view shows mintage, current realised price tier and rarity for every coin so you can prioritise the cheap easy wins or save up for a single key date.
For collectors who like a goal, the series progress bar is satisfying in a way a spreadsheet never managed. Complete the Beatrix Potter 50p run and you'll see exactly how many you have, how many remain, total acquired cost and current value — all without lifting a finger.
Watchlists, alerts and price history
Anything you don't own yet but want to track goes on your watchlist. Each watched coin shows the latest realised price, 30-day trend, and a price-alert option so you know when something drops into your buying range. This sits alongside the catalogue's liquidity score — how often the coin actually trades — which is critical for serious collectors: a coin that "sells for £500" but trades twice a year is very different from one that sells weekly at £500.
Community, not just data
The community layer is opt-in and lets verified collectors showcase their collections, comment on individual coin pages, and contribute photographs of specimens that the catalogue then incorporates as references. The admin team curates this so the catalogue stays accurate, and verified contributors earn flair badges — small distinctions that recognise consistent quality contribution. The leaderboard ranks public collections by portfolio value, item count and series-completion progress.
Free tools you don't have to subscribe for
Several tools are free to use without an account at all: the UK coin identifier walks you step-by-step through identifying any British coin from photos and physical characteristics; the pre-decimal currency converter handles £sd conversions between pre-1971 and decimal pounds; the mintage rarity calculator tells you where any mintage falls in the UK distribution and shows similar-mintage examples from the catalogue.
Where it's heading
The roadmap is publicly visible: an iOS app (in private beta), an auction-bidding agent that tracks upcoming lots in your watchlist across all eight scraper sources, automated probate valuations, and an expanded US coin coverage to match the British depth.
The goal is simple: give collectors the tools they actually need. No unnecessary complexity, no barriers to entry, just a clean and powerful way to manage and enjoy your collection. MyCoinage is just getting started, but the vision is clear — a single platform where collectors can track, learn, and grow their collections with confidence.
