The U.K.’s Royal Mint has released what it describes as the “most secure coin in the world.” The bimetallic £1 coin, which entered into circulation Tuesday, boasts a hologram-style image, micro lettering and a “hidden security feature” designed to beat counterfeiters...I'd think you'd want to counterfeit bills, which are worth much more, but then, I'm not a counterfeiter and obviously don't think like a counterfeiter.
Approximately one in 30 £1 coins in circulation is a counterfeit, according to the Royal Mint.
And the last paragraph of the article is entertaining:
The U.K. is earning a reputation for innovation in currency technology. Last year the country introduced a new, highly durable “plastic” £5 bill, its first ever bill made from polymer. The bill, however, upset vegans when the Bank of England confirmed that it contains traces of animal fat in the form of tallow.
