100 oz Silver Bars: Are They Worth It for Serious Stackers?
The lowest premium in silver comes with a real liquidity tradeoff. Here's who this format actually makes sense for.

The Case for Going Big
A 100 oz silver bar carries the lowest per-ounce premium of any common silver product — often just a small fraction over spot compared to the 15–25% premiums typical of sovereign coins. For serious stackers accumulating a large position, that premium gap compounds meaningfully over time.
What You Give Up
Liquidity in small increments. You can't sell "a fifth" of a 100 oz bar easily — it's an all-or-nothing sale, unlike a stack of individual coins you can liquidate a few at a time as needed.
Verification friction at resale. Larger bars sometimes require more scrutiny (assay verification, serial number checks) from a buying dealer than a widely recognized coin, particularly for bars from less internationally known refiners.
Storage concentration risk. A single 100 oz bar represents a large dollar value in one physical object — worth factoring into your storage and insurance planning specifically.
Who this actually fits: 100 oz bars make the most sense for investors who've already built a meaningful stack of more liquid products (coins, smaller bars) and are adding a large position specifically to maximize ounces per dollar on new purchases — not as a first-ever silver purchase, where flexibility matters more.
Choosing a Reputable Refiner
Stick to bars from well-established, LBMA-recognized refiners. This matters more for large bars than small ones, since a counterfeit or misrepresented large bar represents significantly more dollar exposure than a single fake coin would.
They offer the lowest per-ounce premium of common silver products, making them cost-efficient for large positions. The tradeoff is reduced liquidity — you can't sell a partial bar — so they're generally better suited to investors who already hold more liquid products and are adding a large position specifically to lower their average cost.
Buy only from established, reputable dealers carrying bars from well-known LBMA-recognized refiners. Serial-numbered bars with an accompanying assay certificate add an extra layer of verification, which matters more for large bars given the higher dollar exposure per unit.
