A Geiger silver bar is worth its silver first: the 20 gram bar holds $33.45 of .999 fine silver and the 1 gram bar holds $1.67 at a $52.07 spot price. What separates Geiger from a generic small bar is the security package built into its square “Geiger original” line — a ribbed edge, UV-reactive security features, and an individual serial number.

Geiger Silver Bar Sizes and Melt Values
Geiger’s signature silver line is the square gram bar, struck at Schloss Güldengossa near Leipzig — the castle pictured on every bar. The gram sizes are the core of the range, and each one is .999 fine silver sealed in a security capsule with its certificate:
| Size | Troy ounces | Melt value |
|---|---|---|
| 1 gram | 0.0321 | $1.67 |
| 5 gram | 0.1606 | $8.36 |
| 10 gram | 0.3212 | $16.72 |
| 20 gram | 0.6424 | $33.45 |
| 50 gram | 1.6059 | $83.62 |
| 100 gram | 3.2119 | $167.24 |
| 1 oz | 1.0000 | $52.02 |
The same square format runs up to 250 gram, 500 gram, and 1 kilo bars, and Geiger also pours and strikes ounce-denominated sizes. The two sizes buyers ask about most are the ends of the gram ladder: the 1 gram, bought as an affordable gram of fine silver in tamper-evident packaging, and the 20 gram, which carries noticeably less premium per gram.

The Security Features Are the Point
Small bars are the easiest bullion to counterfeit, and Geiger’s answer is to make the genuine article hard to copy. The Geiger original silver bars combine several features that generic bars skip:
Ribbed edge. The edge of each square bar is fluted like a coin’s reeding, so a cast copy — the usual fake — shows it immediately.
UV security features. Parts of the bar’s reverse design are printed in a coating that only appears under ultraviolet light; a fake without the UV layer fails a ten-second lamp check.
Individual serial number. Each bar carries its own number, tying it to its certificate.
Pearl-finish security coating and sealed capsule. The bar is sealed at the mint in a rigid capsule with the certificate card, so a bar outside its packaging has lost part of its proof.
No single feature is proof on its own, but the combination is why Geiger bars are treated as the benchmark for small-bar security — and why a Geiger priced far below every other dealer is a reason to walk away, not to hurry.
What “In Assay” Means for a Geiger Bar
Most Geiger silver bars are sold “in assay”: sealed in the capsule with a certificate card stating the weight, fineness, and serial number. The seal is doing real work — it is the mint’s statement that the bar inside is the bar described, and it keeps the surfaces untouched. Bars removed from the capsule are still .999 silver, but they lose the instant recognizability the sealed package gives at resale. Our explainer on what an assay card is covers how these certificates work across brands.
Premiums: Small Bars Cost More Per Gram
Melt is the floor, not the price. Every bar carries a premium over melt for minting, packaging, and distribution, and that premium is a much larger percentage on a 1 gram bar than on a 100 gram bar — the capsule and certificate cost roughly the same either way, spread over 100 times less silver. That is the honest trade in fractional silver: the 1 gram bar is the most expensive way to own silver per gram, and the 20 gram and larger sizes close most of the gap while keeping the security features. Compare any quote against the melt column above; the difference is what you are paying for the format. For the metal value of silver in coin form, see our silver coin melt value guide.
How to Check a Geiger Bar
Start with the capsule: the serial number on the bar should match the certificate, and the seal should be unbroken. Put the reverse under a UV lamp and look for the security design. Weigh the bar in its capsule only against a known-good example — capsule weights vary — so for a bare bar, weigh it directly (a 20 gram bar should read 20 grams) and measure it against the listed dimensions. A dealer-grade check with a device such as the Sigma Metalytics verifier confirms the metal itself without damaging the bar. If a “Geiger” is loose, unnumbered, or missing the ribbed edge, treat it as generic silver until a test proves otherwise.

Geiger Silver Bars FAQ
How much is a 20 gram Geiger silver bar worth?
Its melt value is $33.45 at a $52.07 silver spot price (November 8, 2026) — 20 grams of .999 fine silver is 0.6424 troy ounces. Retail prices sit above melt by the bar’s premium, and buyback offers sit below it.
Are Geiger silver bars .999 fine?
Yes. The Geiger original silver line is struck in .999 fine silver, and each sealed bar’s certificate states the fineness alongside the weight and serial number.
Why does a 1 gram Geiger bar cost so much more than $1.67?
Because $1.67 is only the metal. The capsule, certificate, security features, and minting are fixed costs spread over a single gram, so fractional bars always carry the highest percentage premiums in bullion.
What makes Geiger bars hard to fake?
The combination: a ribbed edge, UV-reactive security features on the reverse, a pearl-finish security coating, an individual serial number, and mint-sealed packaging. Any one feature can be imitated; all of them together, correctly, is a much harder job.
Should I take a Geiger bar out of its capsule?
There is rarely a reason to. The sealed capsule is part of the bar’s proof of authenticity and protects the finish; a sealed Geiger is easier to resell than a loose one.
