The 50g was sold from 2006 - 2015, so that would make yours a 2010 build.

There's a bit more information here about an intermediate format:

In the latest units, the initial 3-letter code stands for which factory; sometimes the country is clear, other times not. Also, the final 4-5 digits represent the unit made during the indicated week, but it's not a simple count, as both letters and numbers are used, sometimes only letters.
