I am looking to invest in Bitcoins by selling off some Krugerrands I own.

What would be the best way to do this? I work in the Bullion industry in the UK so I can sell them and then purchase Bitcoins with the proceeds? is there anywhere I can exchange physical cash for bitcoins?
or is it possible to sell them directly for Bitcoins? if so who/how/where?

and as I am a Noob to Bitcoins any advice to ensure I don't get ripped off?

thanks all
BB
