If you gave a child a hammer and told it to blink when it expects to hear a loud noise then you'd be likely to receive a more accurate service. I think they literally run a sweepstake to see who can get away with the most ludicrous attempt each week. Whack-a-mole is a fairground game, not an assay office qualification.

From Goldsmith's Company Assay Office
For seven centuries London Assay Office has been responsible for testing and hallmarking precious metals. The first UK Assay Office was founded at Goldsmiths' Hall from where the term "hallmarking" originates.
Now we regularly hallmark 2-3 million articles each year at our 4 sites across London.
A hallmark:
- Is a set of component marks applied to articles of gold, silver, platinum or palladium.
- Means that the article has been independently tested.
- Verifies that it conforms to all legal standards of purity (fineness).
- Enables authentication of provenance by telling us where the piece was hallmarked, what the article is made from, and who sent the article for hallmarking.
