How much is a gold bar worth
Weight and fineness first, a dated gold ask as the melt floor, and listed premiums for branded bars.
The app scans faster, keeps a history of your items and gives free weekly scans.
Gold and silver price guides start with weight and fineness, not the brand name on the box. A bar, a bullion coin, and a 14k ring are different amounts of metal. Snap a photo to check yours free.
Example
A Valcambi Suisse 1 oz 999.9 gold bar
Melt is a floor from the exact weight and fineness; branded bars often include a dealer premium
The same Valcambi 1 oz gold bar already used on this site, shown here as a gold and silver price guide example. Jewellery, coins, and scrap are not priced the same way as a stamped bullion bar.

Gold and silver price guides that only quote a live spot price leave out the details that change the number: the exact weight, the fineness, the dealer premium on a branded bar, whether you are holding jewellery or scrap rather than bullion, and whether a gold coin is a one-ounce bullion issue or a collectible date. We treat melt as a floor, cited from a dated source or from a live metal price in the app, and we also look at public listings.
Jewellery marked 14k or 18k contains only a fraction of its weight in gold. A scrap payout is often below a simple melt of that gold content. Stones may add little to a scrap quote. A photo estimate cannot replace an assay or a dealer test when a large sum is at stake, and counterfeit bars exist.
A catalytic converter can have scrap value because of the platinum, palladium, and rhodium in the catalyst, but you should only sell a converter you legally own. We will not invent a national average price for converters. A licensed yard quote, with identification, is the practical check.
Spot prices move through the day and differ slightly by market. Figures we cite on these pages are dated snapshots, often in US dollars. If you are selling, a bullion dealer or a coin shop is the usual route for common bars and coins. The app can draft a listing for eBay, Facebook Marketplace, or Gumtree, but have a high-value piece checked in person first.

Hallmarks, karat marks, and why scrap jewellery is not priced like a stamped gold bar.
Jade value
Jewellery and carvings, not a celebrity headline. Jadeite versus nephrite, colour, and treatment matter more than a per-gram guess.
Catalytic converter value
Only sell a converter you legally own. Identify the unit, then get a lawful yard quote. We will not invent a national average.
How much is my silver worth
Scrap, coins, and bars: weight and purity first, then a dated metal floor and current listings.
Gold coin value
Bullion coins versus collectible dates, with a dated gold ask as the melt floor.

What makes How Much Is It Worth different
One photo is enough to start, and you can add up to two more angles. We identify the item first, you confirm or correct it, then we look up a Worth about figure and a listed range from current public marketplace listings. Those are asking prices, which can sit above what a piece finally sells for. You see the listings themselves when we find enough of them.
Coins and banknotes also draw on Numista. Trading cards use PokéWallet, with a source credit where that data appears. Gold and silver use a live metal price as a floor. If listings are thin, we show a clearly labelled rough estimate rather than inventing a precise number. The app can draft a listing for eBay, Facebook Marketplace, or Gumtree once you are ready to sell. For the short version of this process, read How we price.
FAQ
What do these gold and silver price guides cover?
They start with weight and fineness for bars, coins, and hallmarked jewellery. Melt is a floor from a published metal price. Listed prices for branded bars often include a dealer premium.
Can I scan gold or jewellery online free?
Yes. Photograph the stamped weight, fineness or karat mark, and the refiner or maker, then confirm those details. We use a live metal price as a floor and also look at public listings.
Is jewellery worth the same as a bar of the same weight?
No. A 14k or 18k piece is only a fraction gold, and a scrap payout is often below a simple melt of that gold content. Identify the mark first.
Should I rely on a photo for a high-value bar?
Use the scan as a first range. Counterfeit bars exist. Have a valuable piece tested in person before you buy, sell, or insure it on the strength of a single number.
Can I check a catalytic converter here?
Only if you legally own it, usually from a vehicle registered to you. We will help you read marks and look at public listings when they exist. We will not invent a national average, and we will not help anyone sell a converter they do not own.
