The Royal Mint, Signature

[AClownsPocket]

Just looking for some advice. I have a private pension, a company share scheme I put money into each month and some savings. I'm looking to spread my options, but I'm not some financial wizard. I'm looking for an easy way to put a small amount of money into an account each month and buy gold, silver and platinum. I'm happy to do this over a few years and I'm not looking to take it out in the near term.

The signature option with RM seems an easy way in. After some opinions if there is a better way to do this, is the RM option expensive (1% management charge).

Thanks
