When you buy or sell gold, be very clear on the cost of insured shipping with whomever
you're dealing. Some places include insured shipping, some don't, some do if over a
certain amount, some only for gold, etc..
If the purpose of owning gold or silver is for security during rough times, why put some
one else in the position of being able to grab (or appropriate) your investment? I'd say
keep it at home. The only question then is how to conceal it from thieves.
In California, you can avoid sales tax on the purchase if you buy $1,000 of bullion
or more at one time. If you're buying in California from out of state, it doesn't matter.
You won't pay
California sales tax on the purchase.
Gold coins under an once in weight usually carry a premium on them because the
cost of manufacture is greater per ounce. The good news is that you should get the
premium back when you sell it.
All 1 troy ounce gold coins don't weight 1 troy ounce. Some weigh more. US, Mexican,
British and South African coins contain
additional amounts of silver or copper to
make the coin more durable. Canadian, Chinese and Austrailian coins are 'pure' gold.
In all cases a 1 troy ounce coin contains 1 troy ounce of gold, but the coin may be
heavier due to extra metal.
The Mexcan gold 50 peso is 1.2 troy ounces to be equal to a weight equal to a popular
size in Asia. Odd but true.
If you live in the US you can put gold American Eagles or Silver Eagles in your IRA, but
that means someone else has to hold the coins. Kinda defeats the purpose.

I hope this is useful.
