What is a good size distribution for buying gold?
If the "crash" you worry about is a dissolution of the euro, then the main thing you should concern yourself with is liquidity.  For that, purchase the most highly liquid gold ETF or futures contract, whichever is more appropriate for the total amount of money involved.  Any other way and you will lose a significant chunk of your assets to transaction costs. If, on the other hand, the "crash" you were concerned about were the total collapse of the world economy, and people around the world abandon all paper currencies and resort to barter as a method of trade, then I can see buying several small pieces being a rational strategy, although then I would also question whether you were a sane individual.
