Five kilograms (160.754 troy oz) of 999.5 fine silver from ABC Bullion — Australia's largest privately-owned bullion dealer and LBMA-accredited refinery. The largest single retail silver bar in the ABC Bullion range. At 5kg, the buy premium drops to approximately 6% over spot — a material efficiency gain over the 1kg bar — making it the most capital-efficient silver product available per gram. Stamped with the ABC logo, Australia assay disc, and "5kg SILVER 999.5."
The ABC Bullion 5 Kilogram Cast Silver Bar is the largest single retail silver bar in the ABC Bullion range. Its wide, flat Good Delivery cast format — stamped with the ABC rounded square logo (top-left), Australia assay disc, and "5kg / SILVER / 999.5" (top-right) — is designed to maximise silver density in a manageable physical footprint.
Each bar is individually stamped and produced at ABC Bullion's Sydney refinery under LBMA accreditation. The 5kg bar is suited to investors who have already established a 1kg silver holding and are ready to improve premium efficiency in a single larger-scale purchase. At approximately 6% over spot (ex-GST), it represents the best per-gram price available in the ABC Bullion retail silver range.
As an authorised ABC Bullion dealer, we supply every bar directly from the refinery with full chain of custody. We buy this bar back at 100% of the live spot price.
Investment-grade gold (≥99.5% Au) is GST-exempt under Australian law. Silver does not qualify — all silver bars attract 10% GST regardless of size or purity. Key implications for a 5kg purchase:
The primary reason to buy 5kg over 1kg is premium efficiency. Consider the numbers:
On a 5kg silver holding worth approximately $10,000–$15,000 at current prices, that 2% differential represents $200–$300 in saved premium. The longer the holding period, the less significant the premium becomes relative to price movement — but starting with a lower cost base is always advantageous.
The 5kg is best suited to investors who have already accumulated 5–10kg of silver in 1kg bars and are shifting to larger denominations for efficiency as their position grows.
A 5kg silver bar is a substantial physical object requiring appropriate storage. Key considerations:
Tarnish does not affect silver's melt value or resale price at reputable dealers — it is purely cosmetic. However, vault storage eliminates this concern entirely.
We recommend calling ahead on 1300 000 000 for orders of this size to confirm identification requirements and arrange secure delivery or direct vault placement. A 5kg silver bar weighs 5 kilograms — delivery by specialist high-value insured courier with full replacement-value insurance from dispatch to signed receipt.
In-person collection at our Sydney (Level 10, 1 Martin Place) or Melbourne (Level 8, 360 Collins Street) office is always available at no cost.
At approximately 6% above spot ex-GST, the 5kg bar carries the lowest buy premium of any retail silver bar in the ABC Bullion range — approximately 2 percentage points below the 1kg bar. On a $10,000+ silver position, this represents hundreds of dollars in saved premium cost versus the equivalent weight in 1kg bars.
A 5kg bar delivers 160.754 troy ounces of silver in a single purchase — equivalent to the contents of more than five 1oz gold bars by weight. For investors building a substantial silver position, completing it in one transaction at the best available premium is more capital-efficient than five separate 1kg purchases.
ABC Bullion's full LBMA accreditation makes this bar accepted at face value by any major bullion bank, dealer, or exchange worldwide. The Good Delivery-style cast format and ABC hallmark are recognised internationally — ensuring maximum liquidity whether you sell in Australia, Singapore, or London.
