900 silver is a silver alloy containing 90% pure silver and 10% other metals (typically copper). This silver alloy is known as “coin silver” because it was used in U.S. coinage from 1792-1964.
900 silver is non-magnetic, hypoallergenic (unless allergic to copper/silver), and can be tested using an eraser which leaves black marks when rubbed against genuine 900 silver.
While less pure than sterling silver (92.5%), it’s more valuable than lower-grade alloys like 500 silver.
Today, 900 silver is found mainly in vintage coins, antique jewelry, and some European pieces.
Here’s an awesome quiz on the topic of 900 silver. Take it after you’ve read my guide below.

What is 900 Silver (Meaning and Definition)?
900 silver (also known as coin silver) is a silver alloy that contains 90% silver and 10% other metals, typically copper. 900 silver is called “coin silver” because it was historically used to make coins in the U.S. coinage from 1792-1964.
Nowadays 900 silver is no longer used in coinage and this silver alloy is only found in older coins, vintage jewelry, antique items, and some European silver jewelry.

Hey, being so keenly interested in .900 silver must mean you like genuine, real silver in all shapes and forms, especially as coins and bars.

What is the Melt Value of 900 Silver? How Much is it Worth and is it Worth Anything?

The melt value of .900 silver depends on the current silver market price which fluctuates from moment to moment based on the demand/supply interplay.
To determine the worth of your .900 silver item first you need to measure its weight.
Next, multiply the weight by the silver spot price and then by 0.900 (for 90% purity) to get the melt value.
For example, let’s say the current price of silver is $5 per gram. And your 900 silver object weighs 24 grams.
The exact worth of that 900 silver item would be $5 x 24 x 0.900=$108.

.900 silver is worth much more when sold as collectible items. Some .900 items sell for hundreds of dollars at auctions when their melt value is several time less.
The value there isn’t in the silver content, but in the perceived value of the piece as a whole.
See examples below.

Is 900 Silver Magnetic or Not?
No, 900 silver isn’t magnetic. .900 silver is composed of 90% pure silver and 10% copper. Pure silver doesn’t magnetize, and copper is diamagnetic (copper is weakly repelled by a magnetic field).
For example, coins made from .900 silver should never magnetize no matter the size and power of your magnet.
You have a fake coin if your .900 silver coin starts to magnetize when you test it.
Is 900 Silver Hypoallergenic or Allergenic?
Yes, 900 silver is hypoallergenic because it’s composed of 90% pure silver and 20% copper.
Pure silver is hypoallergenic to everyone except a small group of people with silver allergies.
Copper is hypoallergenic to most people although a small percentage of people in the world is allergic to this metal.
You’ll be allergic to 900 silver jewelry or coins if you’re allergic to copper or silver, or both.

What are the Hallmarks for .900 Silver? Do These Marks Exist?

.900 silver is marked with a numerical stamp of “900”, indicating it contains 90% pure silver and 10% copper.
These items, often antique, may also be marked simply with the word “Coin” or “Standard”. They may also contain maker’s marks, city and assay office marks, date letters and occasionally import/export marks.
Many .900 silver items contain all of these stamps, but many don’t.
Furthermore, coin silver was used to create many coin types, especially in the U.S. Some of these coins were hallmarked with a “900” fineness mark and some weren’t.
Old coins can also have their hallmark erased due to the passage of time and wear and tear (especially true for circulated coins).
The bottom line is that you should clearly see the number 900 engraved on the piece. In small jewelry pieces the number will smaller and more concealed, but should still be there.
.900 silver was at some point in time the silver standard in United States (Coin Silver), China, Argentina, Switzerland, Italy, Yugoslavia, Czechoslovakia, Hungary, Japan, and Egypt.
You’ll see some of those country-specific .900 marks below.

What’s the Difference Between 900 Silver and Silver 875?
The main difference between 900 silver and silver 875 lies in their silver purity. 900 silver is a silver alloy that contains 90% silver and 10% other metals (mostly copper with trace amounts of other metals).
Silver 875 (also known as zolotnik Russian silver) is an alloy of 87.5% pure silver and 12.5% other metals.
This silver alloy contains slightly less pure silver than 900 silver and slightly more copper. Because of higher copper amount silver 875 is more allergenic than 900 silver.
Both silver alloys are hypoallergenic for most people except those with very sensitive skin.

It was widely used in 19th-century American and, historically, Latin American, German, and Chinese jewelry or, silverware due to its durability. | 500 Silver was commonly used in British coins between 1920 and 1946. Occasionally, it is used in jewelry where cost is a significant concern. |

What’s the Difference Between 900 Silver and Nickel Silver?
The difference between 900 silver and nickel silver is that they’re not the same class of metals. 900 silver is an alloy of silver containing 90% silver and 10% other metals (most often copper).
Nickel silver, (also known as German Silver), is an alloy of copper, nickel and zinc without a trace of real silver. Nickel silver is a misnomer because the alloy has no silver but looks a lot like it visually.
900 silver was used in the past in coinage and also for jewelry and cutlery production. But nowadays it’s been supplanted by sterling silver as a superior alloy.
Nickel silver is used in a wide range of applications due to its durability, corrosion resistance, and silvery appearance.
It’s often used as a base metal for silver-plated items, in musical instruments, for jewelry, and in industrial applications like plumbing fixtures and marine fittings.
| Comparison | Silver 900 | Nickel silver |
|---|---|---|
| Composition | 90% silver and 10% copper. | 60% copper, 20% nickel, and 20% zinc. |
| Value | .900 silver is more valuable than nickel silver because it contains more pure silver and less copper. | Nickel silver is less valuable than .900 silver because it contains no pure silver. |
| Tarnishing properties | .900 silver tarnishes slower than nickel silver because it contains less copper than it (copper tarnishes faster than silver). | Nickel silver tarnishes faster than .900 silver because it contains too much copper and no pure silver. |
| Durability | Silver .900 is less durable than nickel silver because it contains less copper (copper is more durable than silver). | Nickel silver is more durable than silver .900 because it contains more copper (copper is more durable than silver). |
| Allergenic properties | .900 silver is less allergenic than nickel silver because it contains less copper and nickel than it (both copper and nickel are more allergenic than pure silver). | Nickel silver is more allergenic than silver 900 because it contains more copper and nickel than it. |
| Common applications | .900 silver was primarily used for American coins before 1965, earning it the nickname "coin silver". It was widely used in 19th-century American and, historically, Latin American, German, and Chinese jewelry or, silverware due to its durability. | Nickel silver is used in decorative items (jewelry, flatware, architectural trim), musical instruments (flutes, saxophones), electronics (contacts, switches, connectors), and precision components (keys, watch parts, springs, ballpoint pen tips). |

Is There Bullion (Coins and Bars) of 900 Silver?
