Most from the UK has hard to create background patterns these days, so you're not limited to the Britannia alone for Royal Mint stuff.
The ping sound is weak on pure gold so such features are convenient for a quick test, for stuff like krugs, kronen, pesos etc. you'd need a real one to compare the sound if we're hit with an EMP killing all electronics ... not aware of tungsten copies that would sound anywhere like the real thing.
I'd just avoid "silent" .999 without security-features like wieners.
