If you are going to take physical position of your gold/silver, I was told to always go with recognizable coins because they are much easier to sell. With a 1oz US/Canadian/kuggerands/etc, you can basically walk in to any coin store around the globe, and they know what you have, and what its worth.
However, if you take a 10/50/100oz gold ingot, the selling process becomes more difficult because they will likely spend more time verifying authenticity, weight, quality, etc. You will eventually get your money, but the selling process will take longer.
