50 gram gold bar: price, size and how it compares

Fifty grams is the size people often skip. Dealer lists jump from 20 g to 1 oz to 50 g to 100 g, and most buyers look at the two ends. Yet the 50 g bar answers a common question neatly: how do I get a low premium without putting five figures into a single bar? Below are the refiners' own measurements, the live gold value, the prices four dealers charged on the morning of 12 October 2026, and a size-by-size comparison of what you pay per gram.

How big is a 50 gram gold bar?

Roughly the size of a postage stamp and only a few millimetres thick. Most 50 g bars on sale are minted, meaning cut from a rolled strip of gold and stamped with a design, then sealed in a card. Here is what the refiners publish.

The Perth Mint lists maximum dimensions within its manufacturing tolerances. The Royal Mint does not publish thickness. See every weight side by side in our gold bar sizes guide.

The Perth Mint bar is 3.10 mm thick at most, which shows how flat minted bars are. A cast bar, poured into a mould, packs the same gold into a shorter, thicker block. Valcambi makes both versions at 50 g. Our guide to cast vs minted bars explains how they are made.

What is a 50 gram gold bar worth today?

Its gold value is 50 grams times the live spot price, the wholesale market price of gold. Dealers sell above this and buy back below it.

What did 50 gram gold bars cost on 12 October 2026?

Our automated check opened each dealer's product page between 07:32 and 07:35 UTC on Monday 12 October 2026, read the price for one bar at the cheapest payment method shown (usually bank transfer or cheque), and compared it with the gold-api.com spot price at that moment. The premium is the extra you pay above the value of the gold.

Spot used (gold-api.com): US$4,186.10 to US$4,187.30, £3,163.32 to £3,163.92, C$5,969.41 and A$5,995.38 per troy ounce. Premium = price / (50 g x spot per gram) - 1. Times: Royal Mint 07:32, Perth Mint 07:32, APMEX cast 07:32 and minted 07:34, Gold Stock Canada 07:33 UTC. Repeat checks appear in our premium tracker.

Two things stand out. First, the spread between dealers is wide: buying direct from the Royal Mint cost about 3.2 to 3.7 percentage points more than the Perth Mint or Gold Stock Canada charged for the same weight. The Royal Mint's prices include delivery and it offers a 2+ bar price of £5,384.83 for its Britannia bar, but on a single bar a specialist dealer is usually cheaper. Second, at APMEX the cast Valcambi bar was only US$15.75 cheaper than the minted one, so the sealed assay card cost very little extra. Our explainer on gold premiums covers what makes up the difference.

Is a 50 g bar cheaper per gram than other sizes?

Yes than smaller bars, and only slightly dearer than 100 g. The fairest test is the same maker and dealer at different weights, so the table below puts our 12 October figures for each dealer's 10 g, 50 g and 100 g bars side by side and turns them into a price per gram.

Premium over spot in brackets. The 10 g and 100 g figures come from the same morning's checks published in our 10 gram and 100 gram guides (06:35 to 06:42 UTC), so spot was within a few dollars. Perth Mint 20 g Kangaroo: A$200.24 per gram (3.82%).

The pattern is clear. Going from 10 g to 50 g cut the premium by roughly 2.5 to 3.3 percentage points at every dealer. Going on from 50 g to 100 g saved much less, under 1 point at the Royal Mint and the Perth Mint. At APMEX the step was bigger (1.7 points), so US buyers gain more by going up to 100 g. In practice, 50 g is where most of the size discount has already arrived. For a list that weighs brands as well as sizes, see the best gold bars to buy.

Who is a 50 gram gold bar right for?

Brands matter for resale more than for price. Bars from LBMA-listed refiners such as PAMP Suisse, Valcambi, the Perth Mint and the Royal Mint are recognised by almost every bullion buyer.

How are 50 g gold bars taxed in each country?

General information only, not tax advice. Country detail: UK gold tax, US gold tax, Canada gold tax and Australia gold tax.

How do you check, store and sell a 50 gram bar?

1. Check the card. Minted 50 g bars come sealed with a serial number that should match the bar. Do not open the seal if you might sell, as an intact card makes resale easier. See what an assay card is.
2. Measure it. Compare length and width with the refiner's figures above. A fake can match the weight but rarely the weight and size together. More in how to tell if gold is real.
3. Store it sensibly. A 50 g bar is small enough for a home safe, but check your contents insurance limit. Options are compared in our gold storage guide.
4. Know the buyback. On 12 October 2026 Hatton Garden Metals listed a buyback price of £4,880.28 for a 50 g bar, about 4.0% below spot. Its own Best Value 50 g bar was listed at £5,233.58 (2.91% over spot) but was out of stock at the time of our check. Buying at that price and selling straight back would return about 93% of what you paid. See selling gold bars.
