When shopping for a 100 gram silver bar, you will encounter two distinct production methods. Understanding the difference helps you choose the right product for your investment or collecting goals.
Molten silver is poured into a mould and cooled slowly. Each bar has a natural, slightly irregular surface that gives it a raw, artisanal character — no two look exactly alike. Lower premium over spot and preferred by stackers focused on accumulation. Examples: Germania Mint 100g, Geiger Edelmetalle Square Bar.
Blanks are punched from rolled silver sheet and struck under high pressure, producing sharp edges, a polished finish, and precisely stamped designs — often with security features. Higher collectible appeal and gift-readiness. Examples: Royal Mint Britannia 100g, Argor Heraeus 100g.
We source exclusively from mints and refiners with verified purity standards, LBMA recognition, and decades of proven craftsmanship.
Germania Mint — Premium Cast Bars
Premium 100g cast bars — .9999 fine silver, LBMA-certified, individually serial-numbered, and secured with a proprietary hologram. Custom-designed collector packaging. A top choice for both stackers and collectors seeking high-purity investment silver.
Valcambi Suisse — The Iconic CombiBar
The iconic 100g CombiBar — a sheet of 100 individually breakable 1g bars. Swiss-made since 1961, LBMA-accredited. Perfect for flexible gifting or staged selling. Unrivalled versatility in the 100g silver bar format.
Geiger Edelmetalle — Distinctive Square Format
Distinctive square-format 100g cast bars from Germany. Each bar is individually foil-sealed with a certificate of authenticity — security and elegance in one. Highly recognisable design makes these a conversation piece as much as an investment.
Argor Heraeus — Swiss Precision Minting
Swiss-made minted bars individually sealed in assay cards with matching serial numbers. One of only four LBMA-approved refiners globally — a standard of trust recognised by bullion dealers everywhere.
Royal Mint (UK) — Sovereign Craftsmanship
The Britannia-design 100g bar from the UK's sovereign mint — recognised worldwide, with strong secondary market demand and exceptional craftsmanship. A prestigious addition to any silver portfolio.
Scottsdale Mint — Collector-Grade Series
High-relief collector-grade 100g bars including the popular Lunar Dragon series. Unique serial number on every bar; arrives in tamper-evident protective packaging. Where bullion investment meets artistic ambition.
The 100g silver bar sits in a practical sweet spot — more silver than a 1 oz coin, at a fraction of the cost of a kilo bar. Here is why this format remains a consistent top seller among serious stackers.
At 3.215 troy oz, a 100g bar holds far more silver than a single 1 oz bar while remaining accessible for investors at every level — no large upfront commitment required.
Silver bars consistently carry lower manufacturing premiums over spot than silver coins of equivalent weight. More silver for your dollar — every time.
A 100g bar fits in a home safe, safe deposit box, or stackable storage case. Standardised weight makes it straightforward to insure, declare, and transport.
Bars from established refiners (Valcambi, Argor Heraeus, Germania Mint) are recognised by bullion dealers worldwide — sell locally or to any online dealer at or near spot.
Physical silver has historically retained purchasing power during monetary inflation and currency weakness. Its dual role as an industrial and monetary metal adds intrinsic demand.
Silver has historically shown low correlation with equities and bonds. Adding 100g silver bars can reduce overall portfolio volatility and improve risk-adjusted returns.
Melt Value Formula
At any silver spot price: Spot Price × 3.215 = 100g silver bar silver value. At $30/oz spot, melt value = ~$96.45. At $35/oz spot = ~$112.53. Every 100g bar is guaranteed to be worth at least this amount regardless of brand or condition — the melt floor is your price floor.

Many 100 gram silver bars sold at BOLD qualify for inclusion in a self-directed Precious Metals IRA. To meet IRS requirements under IRC Section 408(m)(3), silver bars must carry a minimum fineness of .999 and must be produced by a nationally accredited refiner or assayer.
Products from LBMA-accredited refiners — including Valcambi Suisse, Argor Heraeus, and Germania Mint (.9999 fineness) — are widely accepted by IRA custodians. Each product listing at BOLD clearly displays an IRA eligibility badge where applicable.
IRA Investor Note
IRA-eligible silver must be stored in an IRS-approved depository — home storage is not permitted. BOLD can connect you with trusted custodian and vault partners. Learn more about Precious Metals IRAs.
Every 100 gram silver bar sold by BOLD ships with built-in authenticity assurances. Here is what to verify when your bar arrives:
Serial Number Verification
Most premium bars (Germania Mint, Geiger, Argor Heraeus) carry a unique engraved serial number. Record this and store it with your purchase receipt — it is your permanent proof of authenticity and protects resale value.
Hologram or Foil Seal
Germania Mint bars include a proprietary hologram; Geiger bars are individually foil-sealed. Confirm the seal is intact before opening. A compromised seal warrants immediate contact with BOLD's support team.
Assay Card
Products such as the Valcambi CombiBar come with a numbered assay card certifying purity and weight. Keep this card — it protects resale value and is required by most IRA custodians for verification.
Weight Verification
Use a precision scale to confirm 100.0 grams (±0.1g tolerance). Any significant deviation warrants investigation. BOLD provides a full authenticity guarantee on every bar — contact us if anything is amiss.
A fireproof, bolted safe suits small-to-medium collections. Keep original packaging intact to preserve assay certification and resale premium.
Off-site security at low cost. Note: bank safe deposit boxes are not FDIC-insured for precious metals — take out a dedicated policy for full coverage.
Fully insured, professionally managed storage — the preferred option for larger holdings and all IRA-held silver. BOLD can refer you to trusted vault partners.
How much is a 100 gram silver bar worth?
The value is determined by the live spot price of silver multiplied by its troy ounce equivalent of 3.215 oz, plus a manufacturing premium. For example, at a silver spot price of $30.00 per troy ounce, the intrinsic silver value is approximately $96.45. All product listings on BOLD display the current price alongside a live spot reference so you can calculate your exact premium before purchase.
What is the difference between a 100 gram and a 100 oz silver bar?
These are very different products. A 100 gram silver bar weighs 100 grams (3.215 troy oz) — a compact, entry-level bullion product. A 100 oz silver bar weighs 100 troy ounces (approximately 3.11 kg) and is a high-value product aimed at institutional buyers or bulk investors. BOLD sells both formats. Browse our 100 oz silver bar collection here.
Are 100 gram silver bars a good investment?
For investors seeking an affordable, liquid, and portable physical asset, 100 gram silver bars offer a strong combination of accessibility and value. They carry lower premiums than silver coins of equivalent weight and are recognised globally for resale. As with any investment, silver prices fluctuate. Most advisors treat physical silver as a long-term portfolio diversifier rather than a short-term trade.
Can I put a 100 gram silver bar in a Precious Metals IRA?
Yes — select 100g silver bars at BOLD qualify for self-directed Precious Metals IRAs. Eligible products must carry a minimum .999 fineness and come from an IRS-approved refiner. Qualifying options include bars from Valcambi Suisse, Argor Heraeus, and Germania Mint. IRA-held silver must be stored in an approved depository. Contact BOLD for custodian and storage referrals.
How do I sell my 100 gram silver bar?
BOLD buys silver as well as sells it. Contact our purchasing team for a quote on your 100g silver bars. You can also sell to any LBMA-affiliated dealer or reputable local bullion shop. Bars from recognised mints with intact assay cards and serial numbers command the strongest resale premiums. Keep your original packaging to protect secondary market value.
What is the premium over spot on a 100 gram silver bar?
Premiums on 100g silver bars at BOLD typically range from a few percentage points above the live silver spot price. Cast bars from Germania Mint and Geiger Edelmetalle generally carry lower premiums than collectible minted bars. All product listings display the current price alongside a live spot reference so you can calculate your exact premium before purchase.
Does BOLD offer free shipping on 100 gram silver bars?
Yes. BOLD Precious Metals offers free, fully insured shipping on all orders of $199 or more. All silver bar orders ship in discreet, tamper-evident packaging. Expedited shipping options are available at checkout for time-sensitive orders.
