Coins are graded on the Sheldon 1–70 scale. For bullion collectors, the key grades are:
MS70
Perfect Uncirculated — no flaws under 5x magnification. Rare, commands 2–5× premium over raw coin.
MS69
Near Perfect — one or two tiny imperfections. Much more attainable, still a significant premium.
MS67
Superb Gem — a few small contact marks. Sweet spot for many collectors.
PR70
Perfect Proof — mirror-like fields, frosted devices. Proof coins are struck multiple times for collectors.
💡 When is grading worth it? Generally only if the coin is worth £500+ and you believe it will grade MS69 or above. Grading fees run £30–£80 per coin via PCGS or NGC. Raw bullion coins rarely need grading unless they're key dates or proofs.
🔎 Counterfeit Detection Basics
Weight & diameter — every genuine coin has published specs. A precision scale (0.01g accuracy) and calipers are essential. A fake will almost always be slightly off.
Ping test — genuine gold rings with a distinctive tone when tapped. The Bullion Test app uses your phone's microphone to analyse the sound signature.
Magnet test — gold is not magnetic. A strong neodymium magnet should have zero attraction. Silver is also non-magnetic.
Edge lettering — Sovereigns have a milled edge, Britannias have lettering. Check it matches the genuine article exactly.
Buy from trusted sources — Royal Mint, major dealers (Chards, Atkinsons, BullionByPost), or coins with PCGS/NGC slabs. Avoid eBay for high-value coins unless the seller has verified authenticity.
📦 Storage Guide
Capsules — best for individual coins. Airtight, protects from handling and humidity. Lighthouse and Quadrum are popular brands. Never use PVC flips — they cause green corrosion over time.
Tubes — for bulk stacking. Hold 20–25 coins of the same size. Less protection than capsules but efficient for large quantities.
Slabs — PCGS/NGC graded coins come sealed in tamper-evident plastic. Best protection possible, no need for additional storage.
Environment — store at 35–55% humidity. Silica gel packets help in safes. Keep away from rubber bands, newspaper, and anything containing sulphur — tarnishes silver rapidly.
Never clean coins — cleaning destroys numismatic value and leaves hairlines visible under magnification. Even a "cleaned" MS65 can drop to MS62.

top 15 nations
Central banks bought 863 tonnes in 2025 — the fourth-largest annual total on record, despite higher prices moderating pace. Poland was the largest buyer (+102t), followed by Kazakhstan (+67t) and Turkey (+27t). Gold overtook US Treasuries late in 2025 to become the world's largest reserve asset by value. The WGC estimates ~57% of 2025 buying was unreported, meaning official figures understate true accumulation. Gold is the only reserve asset with no counterparty risk.
