So, I have too much money and not enough to spend it on. Thus, I've decided I want to dabble in investing, which has led me to looking at gold coins (Britannias in particular). I have very little knowledge about gold and investing other than a few google searches, so could anyone shed light onto the pros and cons of buying gold coins over gold bars? I'm looking at buying an ounce and it will be a long term investment.
Furthermore, Britannias are only 22 carat gold (alloyed with silver since 1990, for those interested). Does this mean that the coin will weigh a spot more than 1 troy ounce to compensate for the lack of perfect purity, i.e. so that the end result contains a troy ounce of 24 carat gold? Or, will the coin be exactly 1 troy ounce (thus not actually containing one ounce of .999 gold due to the extra silver content)? I'm not really sure how this all works and would be grateful if someone could clear it up.
Thanks, Michael
