Silver Britannia Coin Tester Tool Kit - Full, Half, 1/4 & 1/10 Coins
Don't Let a Fake Britannia Become an Expensive Lesson.
£19.95
Following the success of our original Gold Sovereign Tester, the CoinVerify Silver Britannia Tester Kit provides collectors, investors and dealers with a quick and convenient way to screen UK Silver Britannia coins against their expected physical specifications.
The kit covers 1oz, 1/2oz, 1/4oz and 1/10oz Silver Britannias and uses four simple physical checks to help identify coins that may require further investigation.
Both post-2013 and pre-2013 1oz Britannia testers are included. Post-2013 1oz Silver Britannias are struck in .999 fine silver, while earlier coins were struck in .958 silver and have different physical dimensions — so we've included the appropriate tester for both types.
How to use in 4 simple steps:
✓ DIAMETER — Check against the precision-sized gauge
✓ THICKNESS — Pass through the corresponding coin slot
✓ WEIGHT — Compare with the specification shown on the tester
✓ MAGNET — Use the integrated strong magnet to screen for unexpected magnetic metals
Passing all four checks provides a strong indication that the coin matches its expected physical specifications.

IMPORTANT: CoinVerify uses proven physical screening principles to check a coin’s diameter, thickness, weight and magnetic response against its expected specifications, providing a strong indication of authenticity when all checks are passed. For absolute confirmation of metal composition or purity, specialist XRF analysis is recommended where a coin fails a check or remains questionable.
