The coin catalogue
MyCoinage now tracks more than 4,700 British coins with proper mintages, images, rarity scores and realised auction prices. This month we tidied up the catalogue in a big way, every major circulating denomination now has its own series page, from the ½ penny through to £5, with the 5p, 10p, 20p and 2p series newly added alongside the crowns, sovereigns and bullion ranges that were already there. Hundreds of coins that were sitting without a home have been slotted into the right series so you can browse collections properly.
On the Metals page all five precious metals, gold, silver, platinum, palladium and copper, sit on one clean row on desktop with a live chart for each.
Prices, refreshed hourly
The price pipeline that keeps MyCoinage accurate runs four jobs every hour now: currency exchange rates, spot metal prices, every user's portfolio value, and the leaderboard. That's up from three times a day. We also switched the spot feed to a true live-spot source rather than futures, so the gold and silver prices you see match the reference numbers on the rest of the web.
Auction data keeps flowing in from weekly passes over Spink, Baldwin's and Noonans, the three big London numismatic rooms, plus rolling eBay sales verification. Anything flagged by the auto-verifier as an unusual price goes to manual review before it's counted, so dodgy outliers never pull a grade average in the wrong direction.
Scrapers
- The Royal Mint news feed is refreshed every 6 hours for the News page
- The US Mint press-release scraper now pulls the correct publication date on every article (previously they all read as "today") and back-fills dates on existing rows
- A nightly auto-verifier passes through new price submissions, accepting the obviously-normal ones and flagging anything off for an admin eyeball
- A weekly rarity recalculation updates every coin's rarity score based on the latest mintage data, survival estimates, auction volume and condition spread
What's next
We're still actively growing the catalogue, US coverage is on the roadmap, and we're steadily filling in the gaps in older British pre-decimal issues. Expect more coin series pages, more auction data, and more guides over the coming weeks.
