One-ounce silver bars are the most popular way to buy physical silver, and for good reason. They're small enough to be affordable for dollar-cost averaging, liquid enough to sell quickly, and carry lower premiums than coins or fractional sizes.
Unlike silver rounds or coins, bars are typically produced by private mints and refiners — which means you're paying for the metal, not a government mint markup. That translates directly to lower premiums over spot price.
We track premiums across the five largest online silver dealers in the US. Our comparison focuses on three things:
Generic bars (also called "secondary market" bars) are produced by various refiners and sold without a specific brand premium. They carry the lowest premiums — often $1.50-2.50 over spot.
Branded bars from well-known refiners like PAMP Suisse, Valcambi, or Engelhard carry higher premiums ($4-8+ over spot) but also command better resale prices. If you're buying to hold long-term, the brand premium may be worth it. If you're stacking for weight, generics win every time.
Not all silver bars qualify for a Precious Metals IRA. The IRS requires silver to be .999+ fine (which all bars on this list meet) AND produced by an LBMA-accredited refiner or national government mint.
PAMP Suisse, Valcambi, and Sunshine Minting bars all qualify. Many generic bars do not. If IRA eligibility matters to you, verify the specific refiner before purchasing.

For most buyers, SD Bullion's 1 oz silver bars offer the best value — lowest premiums, reliable shipping, and solid customer service. If you want a recognized brand for resale value, APMEX is the safe choice at a modest premium increase.
If you're buying for an IRA, go with PAMP Suisse or Sunshine Minting — both are LBMA-accredited and widely accepted by IRA custodians.
