A 10 oz silver bar holds 10 troy ounces of fine silver, usually .999, which is 311.035 grams. You pay spot plus the dealer's premium on each of those 10 ounces, so the brand, the quantity you buy and the way you pay all show up in the premium rather than in the silver. This guide covers the weight, the arithmetic and single-bar premiums on six 10 oz bars read on 10 November 2026.
What a 10 oz silver bar weighs and contains
A 10 oz silver bar weighs 311.035 grams, because the 10 ounces are troy ounces, not the ounces on a kitchen scale. Appendix C of NIST Handbook 44 defines the troy ounce as 31.1034768 grams, against 28.349523125 grams for the avoirdupois ounce, the everyday ounce.
| Unit | A 10 troy oz bar |
|---|---|
| Grams | 311.035 |
| Kilograms | 0.311 |
| Avoirdupois ounces | 10.97 |
| Avoirdupois pounds | 0.69 |
Fineness is the share of pure silver in the bar, stamped in parts per thousand, so a .999 bar is 99.9% silver. The explainer what is a troy ounce compares troy and regular ounces in more detail.
How a 10 oz bar's price is built
What 10 oz of silver is worth as a bar comes down to two numbers: spot, the market price per troy ounce, and the premium the seller adds per ounce. How spot, premium and the dealer spread are set is explained in the guide to how a bullion trade-in is priced; for a 10 oz bar the arithmetic is (spot + premium per oz) x 10.
Because the bar holds 10 ounces, any change in spot or in the premium per ounce reaches the bar price ten times over. A $1.00 move is $10.00 a bar, and a premium that looks small per ounce is ten times larger on the receipt.
Reading an "as low as" premium on a 10 oz listing
An "as low as" premium is the premium at a listing's largest quantity tier, not the price of one bar. When a listing has only one tier, the two are the same; when it has several, a single bar costs more per ounce than the headline figure.
The Scottsdale Imperium X cast bar shows how wide that gap can be. On 10 November 2026 its listing read "as low as" $3.30 per ounce over spot, which applied at 50 bars or more. One to four bars carried $4.50 per ounce, $12.00 more per bar. The Scottsdale Stacker read $5.41 at 10 bars or more and $5.81 for one to four.
So the first column of a listing's price table, not the headline premium, is the number to compare when you are buying one or two bars.
Single-bar premiums on six 10 oz bars, 10 November 2026
On 10 November 2026, by check or wire, the lowest single-bar premium of the six bars below was the Asahi at $1.83 per ounce over spot and the highest was the sealed Johnson Matthey at $6.46, a gap of $46.30 on one 10 oz bar. They are six of more than 30 10 oz listings at Stout that day, chosen to cover new, sealed, secondary and .9999 bars.
| 10 oz bar | Label on listing | Fineness (as listed) | Premium per oz (one bar) | Premium per bar |
|---|---|---|---|---|
| Asahi | Sealed in plastic (description) | .999 | $1.83 | $18.30 |
| Scottsdale Imperium X | Cast | .999 | $4.50 | $45.00 |
| Scottsdale Stacker | Brand new | .999 | $5.81 | $58.10 |
| CNT Eagle | Cast | .9999 | $6.44 | $64.40 |
| Engelhard | Secondary market | .999 | $6.45 | $64.50 |
| Johnson Matthey | Sealed | .999 | $6.46 | $64.60 |
The listings recalculate as spot moves, so the table is a snapshot of that evening, not a price you can order at. The table also shows that neither cast production nor a higher fineness sets the order on its own: the cast Imperium X sits below the Stacker, and the .9999 CNT bar sits beside the .999 Engelhard and Johnson Matthey bars.
Each listing also prices the same bar twice. The credit card and PayPal price was 3.75% above the check and wire price on every listing checked, and the full set of payment rules is in the guide to buying bullion online.
Worked example: one 10 oz bar by check and by credit card
One 10 oz bar paid by credit card or PayPal costs 3.75% more than the same bar paid by check or wire, on the silver as well as the premium. Call the spot price S. One Asahi 10 oz bar at the single-bar premium in the table is listed at 10 x (S + $1.83), which is 10S + $18.30, by check or wire, before any shipping or tax, which the listing price does not include.
Paid by credit card or PayPal, the same bar is listed at 1.0375 x (10S + $18.30). The dollar gap between the two payment rows therefore moves with spot: the card row adds 37.5 cents for every $1.00 of spot, plus 3.75% of the $18.30 premium.
New, sealed and secondary 10 oz bars
A secondary-market bar is one that has been owned before and is being resold, rather than coming new from the maker; what it holds, and what can differ, is covered in the FAQ below.
Some brand names only appear on older bars. Johnson Matthey completed the sale of its gold and silver refining business to Asahi in March 2015. Johnson Matthey 10 oz bars offered today generally date from before that sale, which is why the one checked here is sold sealed rather than new from the maker. Two of the Engelhard 10 oz listings on the site are labelled secondary market or vintage.
Cast bars are poured into a mold, while minted bars are struck from a blank. How the two methods differ is covered in hand-poured vs minted silver bars.
Six things to check on a 10 oz listing
Check six things before you order a 10 oz bar. Each one affects either the total or what the total buys.
- Weight and fineness: 10 troy ounces, and .999 or .9999 as stated on the listing and stamped on the bar.
- New, sealed or secondary: the label sets what condition to expect.
- Cast or minted: this changes the surface, the weight tolerance and often the premium; the stamp states the silver content.
- Quantity tier: read the first column if you are buying one bar.
- Payment method: credit card and PayPal are priced in the higher row.
- Delivery terms: how the order ships and when coverage ends.
How Stout lists and ships a 10 oz bar
Each 10 oz listing on the site shows an "as low as" bar price and, below the price table by quantity and payment method, an "as low as" premium per ounce above spot; the final price is set at checkout once the payment method is chosen. Current 10 oz silver bars for sale, with stock status, are on the 10 oz silver bars page.
The shop states that its shipments are insured from the time they ship until the package is signed for or left at the delivery address, and that it is not responsible where you have told the carrier to leave a package unattended or with someone else. The terms, including the 2-business-day window to report a problem, are on the shipping and insurance page.

Frequently asked questions
What is a 10 ounce silver bar worth when you sell it?
A dealer's buy price for a 10 oz bar starts from spot and sits below its selling price, and the gap between the two is the dealer spread. The brand, the condition and the market that day set the exact figure, so ask for a quote on the specific bar. The trade-in pricing guide linked above shows how both numbers are built.
Are all 10 oz silver bars .999 fine?
No. Five of the six bars in the table above are .999 fine, while the CNT Eagle cast bar is made to .9999, or 99.99% silver. The fineness is stamped on the bar and stated on the listing, so check that the two match before you order, especially when comparing premiums.
Does a secondary 10 oz bar hold less silver?
No. A genuine secondary bar holds the weight and fineness stamped on it, and the secondary-market listing checked here states that each bar is tested for silver content and purity. What differs is the history: the surface can show handling or toning, and the original packaging may be gone. The listing photos show the condition.
