10 oz Silver Bars: The Sweet Spot

The 10 oz silver bar is the most popular silver bar size at SD Bullion and across the industry. At spot + $1.29-$1.79/oz, the 10 oz bar offers premiums substantially lower than coins while remaining manageable in size and weight (approximately 311 grams or 10.97 ounces avoirdupois).

Popular 10 oz bars include the Sunshine Mint (featuring MintMark SI anti-counterfeiting technology), Asahi Refining (formerly Johnson Matthey's North American operations), and Royal Canadian Mint (99.99% purity). All are LBMA-accredited and IRA-eligible.

For investors dollar-cost averaging into silver on a monthly basis, the 10 oz bar is ideal: low enough premium to maximise ounces per dollar, small enough to store easily, and recognisable enough to liquidate at strong buyback prices through SD Bullion's buyback program.

100 oz Silver Bars: Maximum Weight, Minimum Premium

The 100 oz silver bar carries the absolute lowest per-ounce premium of any silver product. At SD Bullion, 100 oz bars run spot + $0.59-$0.99/oz — on 100 ounces, that is a total premium of just $59-$99 compared to $199-$249 for the same weight in 1 oz bars. The savings are substantial.

A 100 oz silver bar weighs approximately 6.86 pounds (3.11 kg) and is roughly the size of a brick. Major brands include Asahi, Johnson Matthey (vintage, highly collectible), Royal Canadian Mint, and Engelhard (vintage). All are 99.9%+ pure and IRA-eligible from approved refiners.

The trade-off with 100 oz bars is less divisibility. You cannot sell half a bar. For investors with $3,000+ to deploy into silver at once, the 100 oz bar is the most cost-efficient option. SD Bullion ships 100 oz bars free, fully insured, with signature required. Storage solutions are available through SD Bullion's storage partners.

Silver Bar Brands at SD Bullion

Sunshine Mint is the largest private mint in the United States and produces silver bars for the US Mint's American Eagle blank program. Sunshine bars feature the proprietary MintMark SI security mark, verifiable with a decoder lens, providing an additional layer of anti-counterfeiting protection. Sunshine bars are consistently among the lowest-premium options at SD Bullion.

Asahi Refining, one of the world's largest precious metals refiners, acquired Johnson Matthey's North American refining operations in 2015. Asahi bars are LBMA Good Delivery List accredited and carry the distinctive Asahi sun logo. Johnson Matthey bars, no longer produced, are collectible vintage items that often carry slight premiums over current-production bars.

Engelhard bars are another sought-after vintage brand. Engelhard ceased precious metals production in 2006, and their bars now carry collector premiums above generic bars. SD Bullion occasionally stocks vintage Engelhard bars when available through the secondary market. For investors focused on the lowest cost per ounce, current-production bars from Sunshine, Asahi, or the Royal Canadian Mint offer the best value.

SD Bullion sources all silver bars through authorised distribution channels. The United States Mint uses Sunshine Mint blanks for its American Silver Eagle program, underscoring the quality of refiners in the SD Bullion inventory.
