"999 silver," "fine silver," "sterling" — the labels can be confusing. Here's a plain-English guide to what silver purity actually means, and why it matters for a coin you plan to keep.

What "purity" means

Pure silver is a soft, bright metal. Purity — also called fineness — tells you how much of an item is actually silver, versus other metals mixed in. It's written as a number out of 1,000. So 999 silver is 99.9% pure — about as pure as everyday silver gets, which is why it's often called "fine silver."

The common grades

  • 999 (fine silver): 99.9% pure. Bright, soft, and the standard for collectible coins and bullion.
  • 925 (sterling silver): 92.5% pure, with copper added for strength. Common in jewellery and cutlery.
  • 800 silver: 80% pure, older and less common today.

Higher isn't always "better" for every job — sterling's copper makes it tougher for rings you wear daily. But for a coin that's meant to be displayed and treasured, .999 fine silver is the classic choice: purer metal, brighter surface, and unmistakable value.

A .999 mark isn't just a number — it's a promise about what's really in your hands.

Why silver holds value

Silver is both a precious metal and an industrial one — used in everything from solar panels to electronics — so demand comes from two directions at once. That real-world usefulness, plus its long history as a store of value, is why a genuine silver coin always carries worth beneath its design. Unlike a printed certificate or a trophy, the metal itself has a floor.

Caring for a printed silver coin

A few simple habits keep a coin looking its best for decades:

  • Handle by the edges. Fingerprints can mark a bright surface — hold the rim, or wear soft cotton gloves.
  • Keep it dry and capsuled. Store in its capsule or a soft pouch, away from humidity, to slow natural tarnish.
  • Don't over-clean. Harsh polishing can scratch both the silver and a printed design. Gentle is always better.
  • Display out of direct sun. Bright light and heat aren't kind to any keepsake.

The Pixel Collective approach

Every coin we make starts with genuine silver, then takes a full-colour design with a smooth gloss finish — so you get the lasting value of real metal and a picture that means something. It's the best of both: an heirloom you can actually personalise.

This guide is general information to help you understand silver, not investment advice. If you're buying silver as an investment, do your own research and speak to a qualified professional.
