100 oz Republic Metals Corporation Gold Bar

A Legacy Refiner's Largest Gold Bar

The 100 oz Republic Metals Corporation gold bar is one of the heaviest gold bars available to retail investors, containing 3,110.35 grams (100 troy ounces) of 999.9 fine gold. At current prices, a single bar represents a substantial six-figure investment, placing it firmly in the territory of serious portfolio allocators and institutional buyers rather than casual accumulators.

Republic Metals Corporation (RMC) was a Miami-based precious metals refinery that operated as one of the largest gold and silver refiners in North America before filing for bankruptcy in 2018. Its refining assets were subsequently acquired by Asahi Refining in 2019. RMC held LBMA Good Delivery accreditation during its years of operation, and its bars were COMEX-deliverable, meaning they met the London and New York institutional standards for gold bar quality. Bars produced during this period remain fully tradeable and are accepted by dealers worldwide on the strength of the original accreditation.

The 100 oz format occupies a distinctive position in the retail gold market. It is the largest standard bar size most individual investors will encounter. Anything larger, such as the 400 oz LBMA Good Delivery bar, belongs to the institutional wholesale market of central banks and ETF vaults. For buyers seeking to minimise premiums on a large gold allocation, the 100 oz bar delivers near-institutional pricing efficiency in a format that can still be stored in a personal vault or safe deposit box.

Because RMC is no longer producing bars, the 100 oz RMC bar trades exclusively on the secondary market. This does not diminish its value or acceptance; the gold content is identical regardless of the refiner's current operating status, and the LBMA hallmark on each bar serves as a permanent quality guarantee. Secondary-market RMC bars are typically priced competitively against currently-produced alternatives from refiners like Asahi, the 100 oz Royal Canadian Mint bar, or 100 oz Valcambi bar.

100 oz Republic Metals Corporation Gold Bar Specifications

As a cast bar, the 100 oz RMC gold bar has the slightly rough, organic finish characteristic of poured gold. Each bar is individually serialised and stamped with the RMC hallmark, weight, and purity designation. The cast format is standard at this weight class, where minted (stamped) production is impractical due to the bar's size.

At 100 troy ounces, this bar weighs approximately 3.1 kilograms. For context, that is roughly the weight of a standard brick, compressed into a much smaller footprint. Storage requires a substantial safe or vault, and transportation demands secure logistics given the bar's value.

Tax Treatment for the 100 oz RMC Gold Bar

As a 999.9 fine gold bar from an LBMA-accredited refiner, the 100 oz RMC bar qualifies for the most favourable tax treatment available to gold bullion in every major market. The specific rules vary by country, but the purity and accreditation clear all common thresholds.

Purchase Tax

• United Kingdom: VAT-exempt as investment gold (purity exceeds the 995 threshold). However, gold bars are subject to Capital Gains Tax on sale. The annual CGT allowance is currently £3,000, and gains above that are taxed at 18% (basic rate) or 24% (higher rate). Unlike UK legal tender coins such as Britannias and Sovereigns, bars do not benefit from CGT exemption.
• United States: No federal sales tax. Most states exempt bullion from state sales tax. For capital gains, gold is classified as a collectible by the IRS, with long-term gains taxed at a maximum rate of 28% (compared to 20% for equities). Short-term gains are taxed as ordinary income.
• Canada: GST/HST-exempt for gold bars at 99.5%+ purity. Capital gains are taxable at a 50% inclusion rate (66.67% above CAD 250,000 for individuals from June 2024).
• Australia: GST-free as investment-grade gold at 99.5%+ purity. Capital gains attract a 50% discount if held for more than 12 months.
• EU: VAT-exempt under the EU Investment Gold Directive (Directive 98/80/EC) for bars of 995+ fineness.
• Singapore: GST-exempt under the Investment Precious Metals (IPM) scheme for bars of 99.5%+ purity from LBMA-accredited refiners. No capital gains tax applies.
• Hong Kong: No sales tax, no import duty, and no capital gains tax.

Retirement Accounts

In the United States, this bar qualifies for inclusion in a self-directed Precious Metals IRA. The 999.9 purity exceeds the IRS minimum of 99.5%, and the LBMA accreditation satisfies the approved-refiner requirement. The bar must be stored at an IRS-approved depository, not held personally. Given the bar's high value, IRA investors should confirm custodial storage fees, which are typically charged as a percentage of holdings.

In the UK, gold bars of this purity are eligible for SIPP (Self-Invested Personal Pension) inclusion, providing tax relief at the holder's marginal income tax rate.

RMC 100 oz vs Other Large-Format Gold Bars

The 100 oz gold bar market is a niche segment. Few retail investors purchase at this weight, and the field of manufacturers is correspondingly narrow. The key comparison points are brand recognition, current availability, and secondary-market liquidity.

Republic Metals Corporation vs Asahi Refining: Asahi acquired RMC's refining assets in 2019 and now produces bars under its own brand using the same Miami facility. A new Asahi 100 oz bar and a secondary-market RMC bar contain identical gold at identical purity. The practical difference is that Asahi bars are currently produced with full warranty backing, while RMC bars rely on their LBMA hallmark for authentication. Secondary-market RMC bars may trade at a very slight discount to new Asahi bars, representing a marginal cost saving for buyers indifferent to current-production status.

Republic Metals Corporation vs Royal Canadian Mint: The Royal Canadian Mint produces 100 oz gold bars at .9999 fine purity, backed by the Canadian government. RCM bars carry stronger brand recognition and typically command marginally higher premiums. For resale, an RCM bar will find buyers more readily than an RMC bar, particularly outside North America.

100 oz bar vs 1 kg bar: A 1 kg gold bar contains 32.15 troy ounces, roughly one-third the metal of a 100 oz bar. The 1 kg format is more common in European and Asian markets, where metric weights are standard. The 100 oz format is primarily a North American convention. Both formats offer similar per-ounce premiums at the low end of the scale, but the 100 oz bar concentrates more value into a single unit, reducing the total number of items to store and insure.

100 oz bar vs fractional bars: The premium advantage of the 100 oz format is significant. Where 1 oz gold bars carry premiums of 1-4% over spot, and 10g bars run 8-12%, a 100 oz bar compresses premiums to roughly 1-2% over spot. The trade-off is indivisibility: a 100 oz bar cannot be partially liquidated. Buyers who anticipate selling in stages are better served by smaller denominations.
