Silver building blocks from Monarch Precious Metals are one of the most recognizable novelty bullion products on the market. Each block is minted from .999 fine silver and designed with raised studs on top and hollow tubes underneath, creating a functional interlocking system that lets you build structures the same way you would with toy bricks. They have been in continuous production since 2018, and what started as a single 1 oz block has expanded into a full product line spanning seven sizes.
The appeal is simple. Every block contains .999 pure silver with real metal value, but the interlocking design makes them more engaging than a flat bar sitting in a tube. They are popular as gifts, conversation pieces, and entry points for younger collectors who might not get excited about a standard silver bar but will immediately pick up a silver brick and start building.
The Full Product Line
Monarch’s building block lineup has grown well beyond the original 1 oz brick. The current catalog includes seven sizes across two brick formats, all fully interlocking with each other.
1 oz Silver Building Block (2×4)
The flagship product. One troy ounce of .999 fine silver in a 2×4 brick format with eight raised studs. This is the block that launched the line and remains the most popular size. It is available individually, in a 12-block Starter Kit, or in the 120-piece Master Builder Pack for serious collectors. The 1 oz block is the best value in the lineup on a per-ounce premium basis. Compare 1 oz building block prices across dealers.
1/2 oz Silver Building Block (2×4 and 2×2)
Half-ounce blocks are available in two configurations: a 2×4 rectangular brick (eight studs) and a 2×2 square brick (four studs). Both interlock fully with the 1 oz blocks and with each other. The smaller size and lower price point make them accessible for gifts and younger collectors. Available individually or in the 24-block Planner Pack. Compare 1/2 oz building block prices.
1/4 oz Silver Building Block (2×4 and 2×2)
Quarter-ounce blocks in both rectangular and square formats. These are the middle tier of the fractional sizes, offering more building flexibility than the 1/2 oz blocks while keeping the per-block cost under $35. Both formats interlock with all other sizes in the line.
1/8 oz Silver Building Block (2×2)
The smallest block in the lineup. A 2×2 square brick containing one-eighth of a troy ounce of .999 fine silver. At a per-block price under $15, these are the most affordable entry point into the building block line and work well as stocking stuffers, party favors, or small gifts. Like all sizes, they interlock with the larger blocks.
10 oz Silver Building Block
The largest single block Monarch produces. Ten troy ounces of .999 fine silver in one oversized brick. This is the centerpiece product for display builds or for collectors who want significant silver weight in the building block format. It carries a lower per-ounce premium than the smaller sizes (roughly 20% over spot versus 30%+ for the 1 oz), though availability is inconsistent and it frequently sells out.
Pack Options
Monarch offers several curated packs alongside individual blocks. Each pack ships in a collectible tin.
| Pack | Contents | Total Silver |
|---|---|---|
| Starter Kit | 12 x 1 oz blocks | 12 oz |
| Planner Pack | 24 x 1/2 oz blocks | 12 oz |
| Accessory Set | 40 mixed fractional blocks (1/2, 1/4, 1/8 oz) | 12 oz |
| Master Builder Pack | 120 x 1 oz blocks | 120 oz |
The Starter Kit and Master Builder Pack offer the best per-ounce value. The Accessory Set provides the most building versatility with its mix of sizes but carries a higher per-ounce premium. Monarch also sells a solid walnut wood building base designed for displaying block structures. For pricing on the packs, see the 12-pack comparison and 120-piece Master Builder comparison.
Current Pricing and Premiums
Silver building blocks are specialty bullion, and the premiums reflect that. With silver near $64 per ounce, here is how the per-ounce cost breaks down by size.
| Size | Typical Dealer Price | Approximate Premium Over Spot |
|---|---|---|
| 1 oz (2×4) | $79 to $89 | 23% to 39% |
| 1/2 oz (2×4 or 2×2) | $42 to $49 | 31% to 53% |
| 1/4 oz (2×4 or 2×2) | $28 to $30 | 75% to 88% |
| 1/8 oz (2×2) | $13 to $15 | 62% to 82% |
| 10 oz | ~$778 (when available) | ~21% |
For context, a generic 1 oz silver bar from a major refiner typically carries a premium of 5% to 10% over spot. The building blocks run roughly 3 to 4 times that on the 1 oz size. You are paying for the interlocking design, the smaller-batch production, and the novelty appeal. Fractional sizes carry even higher premiums, which is consistent with all fractional silver products, not just building blocks.
The premium means building blocks are not the most cost-efficient way to accumulate silver weight. For lowest-premium silver, check the closest-to-spot silver page. But premium is not the only consideration: these blocks hold their resale value well in the secondary market precisely because of the design premium, and that premium tends to be stable or increase over time as earlier production runs become harder to find.
Where to Buy
Silver building blocks are widely distributed. Monarch sells direct through their own website, and the blocks are carried by most of the major online bullion dealers. Pricing varies between dealers, and the spread can be significant on specialty products like these.
To find the lowest available price on any given day, use the FBP comparison pages linked above or the best silver bullion prices page to compare across tracked dealers. Prices change throughout the day as dealers adjust to spot price movements.
Building blocks also appear regularly on eBay, both from authorized dealer storefronts and from individual resellers. Secondary market pricing on eBay tends to run slightly above dealer pricing for individual blocks, though bulk lots and toned or patinated blocks can command collector premiums above the standard price.
Who Makes Them
Monarch Precious Metals is based in Medford, Oregon, where they have operated since 2008. They specialize in hand-poured and specialty silver products alongside standard bars and rounds. The building blocks are their most recognizable product line.
No other refiner currently produces a competing interlocking silver brick. Other mints make novelty-shaped bars (skulls, animals, gaming dice), and some make stackable bars designed to sit flat on top of each other, but the functional interlocking stud-and-tube design is unique to Monarch. That exclusivity is part of what supports the premium. For more Monarch products, see the Monarch Precious Metals collection.
Gold Building Blocks
Monarch has also introduced building blocks in gold. The gold blocks use the same interlocking design as the silver line and are produced in .999 fine gold. Availability is more limited than silver, and the per-block price is obviously much higher. Gold blocks are a deep-niche collectible product rather than a practical way to accumulate gold weight, but they exist for collectors who want to extend the building block concept into a second metal.
Are Silver Building Blocks a Good Investment?
That depends on what you mean by “investment.” If the goal is to accumulate the most silver for the least money, building blocks are not the right product. The 23% to 39% premium on a 1 oz block means you are paying $79 to $89 for $64 worth of silver. A generic 1 oz bar with a 7% premium gets you the same amount of metal for around $68.
But premium recovery on resale is stronger than you might expect. Because Monarch is the only producer and the blocks have genuine collector appeal, secondary market prices tend to hold above generic bar levels. Sellers on peer-to-peer platforms and eBay routinely get more than melt value for used blocks. The design premium does not evaporate on resale the way it does with some other novelty products.
The most practical approach is to build your core silver position in low-premium bars, Silver Eagles, or closest-to-spot products, and then add building blocks as a fun supplement to the collection. That way you get cost-efficient weight accumulation and the enjoyment of building, without paying novelty premiums on your entire stack.

Frequently Asked Questions
Are silver building blocks real silver?
Yes. Every block is minted from .999 fine silver (99.9% pure). The silver content is stamped on each block. They are genuine bullion products with real metal value, not plated or filled.
Do silver building blocks interlock with each other?
Yes. All sizes in the Monarch line (1/8 oz through 10 oz) use the same stud-and-tube interlocking system and are fully compatible with each other. You can mix 1 oz, 1/2 oz, 1/4 oz, and 1/8 oz blocks in the same build. They do not interlock with plastic toy bricks from other manufacturers.
What sizes are available?
Monarch currently produces seven configurations: 1/8 oz (2×2), 1/4 oz (2×2), 1/4 oz (2×4), 1/2 oz (2×2), 1/2 oz (2×4), 1 oz (2×4), and 10 oz. Pack options include the 12-block Starter Kit, 24-block Planner Pack, 40-piece Accessory Set, and 120-piece Master Builder Pack.
Who makes silver building blocks?
Monarch Precious Metals, based in Medford, Oregon. They are the original and currently the only producer of interlocking .999 fine silver building blocks. No other refiner makes a competing product with the same stud-and-tube interlocking design.
Where can I buy silver building blocks?
Direct from Monarch Precious Metals or from most major online bullion dealers. Use the 1 oz price comparison and 1/2 oz price comparison pages to find the lowest current price across tracked dealers.
Are silver building blocks worth the premium?
The premium is higher than generic silver bars (23% to 39% on the 1 oz vs. 5% to 10% for a generic bar). You are paying for the interlocking design, the novelty factor, and the single-manufacturer exclusivity. Whether that is worth it depends on whether you value the building and display experience or are purely focused on accumulating silver weight at the lowest cost per ounce.
Can I sell silver building blocks for more than melt value?
Generally yes. Because Monarch is the sole producer and the blocks have collector appeal, secondary market prices consistently run above the melt value of the silver content. Resale premiums are not as high as the original purchase premium, but you are unlikely to sell at melt unless you need an immediate liquidation. For general selling guidance, see the selling bullion guide.
