Introducing
Britannia Stack
A Free Tool to Track Your Silver Coin Collection
WEDGE TAILED EAGLE 1oz · PERTH MINT
If you have spent any time collecting silver bullion or modern numismatic coins, you know how quickly keeping track of your stack becomes a chore.
Between standard bullion pieces, proof strikes, privy marks, and multi-ounce releases across different series, spreadsheets soon turn messy. It is easy to lose track of which date runs you have completed, which gaps remain in your collection, or what your stack is genuinely worth above live spot price.
That is why we built Britannia Stack, a free, lightweight web app designed specifically to help collectors organise, value, and manage their silver collections without hassle.
Why Use Britannia Stack?
Britannia Stack sits directly alongside our guides on britannia-uk.com. While our reference guides help you identify coin specifications, mintages, and key variations, Britannia Stack gives you a dedicated personal space to catalogue what you actually own.
There are no paid tiers, no monthly subscriptions, and no complicated account setups. You sign in using a simple email magic link, no passwords to remember and gain instant access to a multi-collection tracker.
Key Features Built for Silver Collectors
Multi-Collection Catalogue
Track a wide selection of popular sovereign silver coin series in one place, including:
Royal Mint Issues: Silver Britannia, Queen’s Beasts, Tudor Beasts, and Lunar series.
North American Classics: American Silver Eagle and Canadian Silver Maple Leaf.
Perth Mint Wildlife & Series: Kookaburra, Koala, Wombat, and Australian Lunar issues.
International Favourites: Chinese Silver Pandas, Mexican Libertad, and more.
Where relevant, series are organised by strike type, separating standard bullion, proofs, coloured finishes, privy marks, and special edition releases so your records remain precise.
Easily Spot Missing Coins In Your Collection
Log exact quantities owned for each edition. The app highlights complete series and flags missing coins in date runs, giving you a clear view of what you need to hunt down next.
When you identify a gap in a date run, Britannia Stack provides direct links to pre-filtered eBay search results (including sold and completed listings research) to help you check recent market prices and find missing pieces.
Realistic Portfolio Valuation (Spot + Custom Premiums)
A silver stack is rarely worth just its melt value. Britannia Stack tracks your portfolio using live silver spot prices while allowing you to assign custom premium values to individual coins. Find direct links to pre-filtered eBay sold & completed listings to help you check recent market prices for an up to date valuation. This gives you an accurate reflection of your stack’s real market value based on what specific pieces command over spot.
90-Day Spot Price Chart
Monitor your total stack value plotted against a 90-day silver price history chart, updated daily. Helping you track how market fluctuations affect your overall silver holding over time.
Collection Insights & Breakdown Charts
View visual breakdowns of your holdings. Insights charts group your collection by release year, series, rarity, and total weight, giving you a clear picture of how your portfolio is distributed.
Account for “Other Silver”
If you hold silver outside the structured catalogue, such as poured bars, junk silver coinage, or niche art rounds, you can log additional silver weight and custom values so your total portfolio calculation remains complete.

– Anyone looking for a free, clean cataloguing tool without ads or paywalls.
