Quote from: ConanMKYou are probably right about the "her Majesty's Navy" bit.

I am genuinely interested in this, so any other errors you could point out would be most appreciated.

The history of British coinage can be confusing. Why are Sterling Pounds incorrect? After readign through the Pound Sterling Wikipedia page (http://en.wikipedia.org/wiki/Pound_sterling), I don't see anything that screams this was an error. What coins should they be using?

Sterling is the name of the currency, but we don't call the currency in use Sterlings.  I'm also not persuaded it can be made into a plural, we have Sterling, we don't have Sterlings.

So, although Sterling is the legal name for our currency, nobody native would call our cash that in the context of actual spending money, you'd only really use that in a foreign exchange or banking context.  I don't go to the shop and spend Sterlings, however I might trade Sterling for Yen if I were a forex trader.

It's an easy mistake for someone who's never been here to make I guess, but really jarring if you're a native.  Our currency is Sterling denominated, but we spend pounds and pence (and back then shillings, groats, all kinds of great names, just not sterlings).
