At East Grinstead Coins, we offer professional precious metal testing services using industry-leading XRF and Sigma Metalytics testing equipment. Whether you are a collector, investor, dealer or simply want peace of mind, we can accurately test your items quickly and without causing any damage.
Our testing service is available from just £5 per item.
Non-Destructive Precious Metal Testing
One of the biggest concerns when testing precious metals is avoiding damage to valuable items.
Unlike traditional acid testing methods, our equipment allows us to analyse and authenticate precious metals without scratching, drilling, cutting or damaging your items.
This means your bullion, jewellery or coins remain in exactly the same condition after testing.
XRF Precious Metal Analysis
We use professional X-Ray Fluorescence (XRF) technology to analyse the composition of precious metals.
XRF testing can identify:
Gold purity
Silver purity
Platinum content
Palladium content
Base metal content
Precious metal percentages
Hallmarked and non-hallmarked items
The test takes only a few moments and provides detailed information about the metal composition of your item.
XRF testing is widely used throughout the precious metals industry because it is fast, accurate and completely non-destructive.
Sigma Metalytics Bullion Testing
Alongside XRF analysis, we also use Sigma Metalytics testing equipment.
Sigma testing is specifically designed for bullion authentication and can verify precious metals beneath the surface without damaging the item.
This allows us to test:
Gold bars
Silver bars
Gold coins
Silver coins
Bullion rounds
Investment-grade precious metals

Sigma Pro Testing
Sigma Metalytics testing is one of the most trusted methods for authenticating bullion products. The technology measures the electrical resistivity of a metal and can analyse beneath the surface of a bar or coin without causing any damage. This allows us to identify many counterfeit or plated items that may appear genuine to the naked eye. Sigma testing is particularly effective for gold bars, silver bars and investment-grade bullion, providing an additional layer of confidence when buying, selling or verifying precious metals.
XRF Testing
XRF (X-Ray Fluorescence) testing is a fast, highly accurate and completely non-destructive method of analysing precious metals. Using advanced technology, our XRF analyser can identify the composition and purity of gold, silver, platinum and other metals within seconds. Unlike traditional acid testing, there is no need to scratch or damage your items, making it an ideal solution for testing bullion, coins and jewellery while preserving their condition.
