Cheapest in-stock total for one coin including delivery, divided by fine gold content. Out-of-stock coins are excluded, which is why a row can be missing on a given day.
Method
For each gold coin in the basket we take the cheapest in-stock total for one unit today and divide by its fine gold content to get a price per gram of gold. We compare each coin with the 1oz Gold Britannia. The gap is what you pay for divisibility: the ability to sell a small part of a holding, and the lower outlay per coin.
