Silver experiment, fake or genuine

Previously, I posted some fake silver and gold coins that was brought from China. Therefore, it is our responsibilities to avoid this matter occur to the public as people are now getting more interest to the precious metal than money. This are the guidelines that you MUST know especially when buying on the internet.

Weight experiment
Weight experiment - generally, fake silver coins are less heavy than genuine because the fake one made from silvery metal alloys. Besides, the weight range must be precise between -0.015 or +0.015. For example, 1/4 oz is equal to 7.78 g. If the scale are more or less than the range itself, it could be a fake.

Surface experiment
Surface experiment - fake silver coins maybe or none of it have a silver-plated finish on them. The genuine silver are more shiny and reflect in lighting spot while the fake are soapy and less shiny. Test under lighting spot and move 360 degree forward and backward continuously. Less reflection means fake.

Reeded experiment



Reeded experiment - this is one of interesting experiment. If you can see details, silver or gold coins do have edge reeding in view elevation. Reed is the line marked at the edge of coin to show the weight ratio are correct without using weight scale. There are 2 types of reeding which are "fine reeding (FR)" and "course reeding (CR)". Simple test, 1/2 oz = 15.5g. Therefore the reeding should have 155 -158 reed.


p/s: Try this at home and you will regret :)
