UK · Gold bars by weight
20 g gold bar
For a 20 g gold bar, declared weight, fineness and refiner are the starting points for comparison. Size alone does not determine purity or the current selling price.
20 g is 11.1035 g below one troy ounce. A lower ticket price than a 1 oz bar therefore does not by itself mean a cheaper offer. Two 10 g bars provide the same stated weight in separately sellable pieces.

Compare sizes and editions
The reference size is 20 g, approximately 20 g or 0.643 troy ounces. For coins, this comparison refers to the 1 oz edition; fractional sizes are separate variants. Always verify the listing’s weight and fineness. 20 g is 11.1035 g below one troy ounce. A lower ticket price than a 1 oz bar therefore does not by itself mean a cheaper offer. Two 10 g bars provide the same stated weight in separately sellable pieces.
Calculate the price per gram
Divide the delivered price by declared fine-gold weight. Illustrative arithmetic, not a market quote: at 100 GBP per gram of fine gold, 20 g gives a hypothetical metal value of 2,000 GBP. A real offer adds a premium and delivery. If the stated weight is gross weight, calculate fine-gold weight first.
A troy ounce and a metric gram are both used in UK bullion offers. Compare the same fine-gold amount in pounds; a coin’s face value is not the amount you pay or its metal value.
Buying and delivery · UK
For a United Kingdom purchase, compare the delivered total in pounds sterling. A euro or US dollar quote is not directly comparable until conversion, delivery and any import costs are included.
Confirm UK delivery coverage and insured handover. A seller dispatching from outside the UK can have different shipping and import terms. Keep tax questions separate from a product’s name and check current HMRC guidance for the exact item and your circumstances.

What is the weight of a 20 g gold bar?
The reference size is 20 g, approximately 20 g or 0.643 troy ounces. For coins, this comparison refers to the 1 oz edition; fractional sizes are separate variants. Always verify the listing’s weight and fineness.
Why is there no fixed price?
The selling price depends on the gold market, refiner, seller, premium and delivery. An example amount is not a current offer. The seller’s price at purchase is authoritative.
How do I check a specific product?
Match weight, fineness, refiner or mint, issue year and packaging to the official source. A photo or certificate alone does not replace verification by a trustworthy supplier.
