About Nadir Silver Bars
Nadir Metal Rafineri A.Ş. is a precious-metals refiner based in Istanbul, Turkey. The company traces back to 1967, when it began as a jewelry-recycling workshop, and moved into precious-metals refining in 1975. It was later formalized as Nadir Trading and, over subsequent restructurings, became Nadir Metal Rafineri A.Ş. in 2006.
Nadir is listed with Borsa Istanbul and the Dubai Multi Commodities Centre, and holds LBMA Good Delivery accreditation — for gold since 2011, when it became the first Turkish refiner to receive that status, and for silver since 2012, a distinction it continues to hold as the only Turkish refiner with LBMA Good Delivery accreditation for silver.
Unlike Engelhard or Johnson Matthey, whose bullion-bar businesses are discontinued, Nadir is an active, currently producing refiner. Nadir bars found in the U.S. market are current production, not vintage secondary-market pieces.
How to Identify a 10 oz Nadir Silver Bar
The front typically carries incuse (struck-in) markings, including the Nadir logo, wording such as “Nadir Metal Rafineri” and “Istanbul,” weight wording such as “10 oz,” a “999.9” or “.9999 fine silver” purity mark, and an individual serial number, often near an assayer's mark.
The reverse is typically blank aside from natural casting texture and striations left from the pouring and cooling process — this is expected for a cast bar and not a sign of an incomplete or altered bar.
Many Nadir bars are issued with a matching certificate of authenticity listing the weight, fineness, and serial number. If present, bring the certificate with the bar, though its absence does not by itself indicate a problem.
Cast Bar Format
The 10 oz Nadir bar is predominantly produced as a cast or poured bar rather than a struck or minted one. Molten silver is poured into a mold and allowed to cool, which gives each bar a slightly individual surface and can leave natural texture, striations, or small mold irregularities. These characteristics are a normal part of the casting process, not damage, and dimensions can vary marginally between individual bars as a result.
Are Nadir Silver Bars Rare?
No. Nadir is an active, currently producing refiner, and its 10 oz bars are widely available through major bullion dealers as current inventory. Nadir bars should not be priced or marketed as rare or vintage collectibles the way some discontinued brands sometimes are.
That said, LBMA Good Delivery accreditation gives Nadir meaningful standing as a recognized refiner, which supports resale confidence even without a collector premium attached.
Nadir Bars vs. Generic 10 oz Silver Bars
Both may contain the same 10 troy ounces of silver, but refiner accreditation can separate the two in the resale market.
| Feature | Nadir Bar | Generic 10 oz Bar |
|---|---|---|
| Manufacturer recognition | LBMA Good Delivery accredited refiner | Varies, often lower |
| Silver content | 10 troy oz | 10 troy oz |
| Typical purity | .9999 fine | Usually .999 fine |
| Current production status | Active, current production | Often still in production |
| Format | Cast/poured | Cast, poured, or minted |
| Certificate of authenticity | Often included | Varies by seller |
| Collector demand | Minimal; priced as bullion | Usually minimal |
| Authentication considerations | Counterfeit and replica bars exist industry-wide | Counterfeit bars exist industry-wide |
| Primary pricing factors | Silver value plus standard bullion premium | Silver value plus modest premium |
A generic bar is not automatically fake or inferior. The right choice depends on whether you prioritize the lowest cost per ounce or a bar from a recognized, accredited refiner.
Nadir vs. Vintage Refiner Bars (Engelhard, Johnson Matthey)
Nadir is best understood as an actively producing, accredited refiner rather than a vintage or discontinued name.
| Feature | Nadir | Engelhard / Johnson Matthey |
|---|---|---|
| Production status | Active, current production | Discontinued |
| Market source | New retail inventory | Secondary market |
| Variety depth | Limited — current standardized design | Multiple documented historic varieties |
| Collector premium | Minimal; priced as bullion | Can be meaningful, depending on variety |
| Refiner accreditation | LBMA Good Delivery (silver, since 2012) | Historic refiner reputation |
| Certificate of authenticity | Commonly included | Varies; not standard across all varieties |
Neither type is inherently better. Nadir suits buyers who want a recognized, accredited, current-production bar at a standard premium; vintage brands appeal to buyers seeking discontinued-brand collector interest.
Original Packaging and Condition
Nadir bars are commonly encountered sealed in plastic with an accompanying certificate of authenticity. Original packaging and the matching certificate can support a faster evaluation, so keep both together if you have them.
Do not clean or polish the bar. Surface marks generally do not change silver content but can affect presentation and buyer confidence. Natural casting texture on the reverse is not damage and should not be treated as a defect.
Testing and Authentication
Counterfeit and silver-plated imitations of recognized refiner brands are a documented concern across the bullion market. Our evaluation looks at weight verification, dimensional review, and visual examination, along with comparing logo, serial-number style, and casting characteristics against documented genuine examples. We also use precious-metal verification equipment, which can include XRF, conductivity testing, or density testing where appropriate.
No single check is relied on in isolation. Every bar we sell is verified through these methods before it ships.
Our Take
Nadir is a legitimate, LBMA-accredited refiner producing current bullion, which gives its bars solid resale standing without the collector-variety complexity of discontinued brands. Buyers should not expect or pay a vintage-style collector premium for a Nadir bar — its value case is recognized accreditation and standard bullion liquidity, not scarcity.
Keep the original certificate of authenticity and packaging together with the bar, since intact packaging helps preserve the surfaces and supports resale later.
Customers focused only on accumulating ounces at a standard premium are well served by 10 oz silver bars like this one. Buyers specifically seeking discontinued-brand collector interest may prefer vintage Johnson Matthey or Engelhard bars instead.

Yes. Nadir Metal Rafineri A.Ş., based in Istanbul, Turkey, is an active precious-metals refiner currently producing gold and silver bars. Unlike discontinued brands such as Engelhard or Johnson Matthey, Nadir bars are current production, not secondary-market-only.
Yes. Nadir Metal Rafineri holds LBMA Good Delivery accreditation for silver, awarded in 2012, and was also the first Turkish refiner to receive LBMA Good Delivery accreditation for gold in 2011. It is also listed with Borsa Istanbul and the Dubai Multi Commodities Centre.
The 10 oz size is typically a cast or poured bar with incuse (struck-in) markings, including the Nadir logo, refinery name, weight, fineness, and an individual serial number. The reverse is usually blank aside from natural casting texture from the mold.
Many Nadir bars are issued with a certificate of authenticity listing the weight, fineness, and serial number. Bars we sell ship with their certificate when one was issued, though a missing certificate does not by itself indicate a problem with the bar.
A blank or lightly textured reverse is a normal, expected feature of cast Nadir bars, reflecting the pouring and cooling process rather than a struck design. It is not a sign of damage or an incomplete bar.
Nadir carries meaningful recognition as an LBMA-accredited refiner, which can support resale confidence compared with an unknown private mint. That said, as a current-production brand it is not treated as a vintage collectible the way discontinued brands like Engelhard or Johnson Matthey sometimes are, so pricing tends to track closer to standard bullion premiums.
No. Cleaning or polishing a silver bar can create surface damage and does not add value. Bring the bar in as-is or text photos before doing anything to it.
We evaluate weight, dimensions, and visual details, and compare the logo, serial-number style, and casting characteristics against documented genuine examples. We also use precious-metal verification equipment, which can include XRF or conductivity testing where appropriate. No single check is relied on by itself — authentication is based on the full picture.
Utah exempts investment-grade precious metals from sales tax, so no sales tax is added to bullion orders like this one. Tax treatment in other states varies, and any applicable tax is calculated at checkout.
