Hello,
Here is a list of the certifications from the UK. I've only included the highest certification of a certain title. The UK also has a Silver certification, this is for the sale of 60,000 copies. Gold is for 100,000 copies and Platinum indicates that the record has sold 300,000 copies. Take also notice of the latest certification date of a certain title, some certifications are more than 15 years old, so who knows what the actual number is...
