Selling Circuit Boards and E-Scrap: Yard by the Pound or Refiner by Assay

A pound of ceramic CPUs holds roughly 10 grams of gold, worth about $650 at March 2026 spot. Buyers pay $2.90 to $4.10. That gap is not a swindle: refining consumes 60 to 80 percent of theoretical value. Understanding it is the difference between selling boards sensibly and chasing a number that was never available.

Why nobody pays gold spot for your boards

This is the first thing to settle, because it explains every price on this page.

Scrap boards genuinely contain precious metal. Recyclers cite circuit boards as holding 40 to 800 times more gold than equivalent gold ore, and the gold sits in three places: edge connectors, CPU pins, and the bond wires inside IC chips.

Now the arithmetic that disappoints people. Ceramic CPUs weigh about 18 g each and carry roughly 0.4 g of gold, so a pound holds about 25 units and near 10 g of gold. At the March 2026 spot price of about $65 a gram, that is $650 of contained metal. Buyers pay $2.90 to $4.10 a pound.

The reason is not margin. Acid, labour, safety and waste disposal consume 60 to 80 percent of theoretical value, and the remainder covers yield risk and freight. No legitimate buyer pays per gram of contained gold; they pay per pound of material against expected recovery.

So the useful question is never “how much gold is in this.” It is which buyer, at which grade, for what volume.

The gap that actually costs you money

Most yards cannot assay boards. They grade everything as generic mixed circuit board scrap.

That is a three to seven times difference on identical material, and it exists purely because one buyer can identify what it is and the other cannot. The buyer routing guide covers the same pattern across other parts.

Board grades and 2026 prices

Older boards are worth more. Boards from the 1990s and earlier carry thicker gold plating than modern equivalents, which is why vintage large-socket boards outprice current ones by several times.

A single desktop motherboard weighs 300 to 500 g and contains 0.1 to 0.3 g of gold, so think in single dollars per board, and considerably more if the CPU and RAM are sold separately.

Components are worth more than the boards they sit on

This is where the money is, and it takes an afternoon.

Stripping RAM and CPUs off boards can raise the value of a lot by over 300 percent. Selling a motherboard with the processor and memory still attached leaves money on the table, and the buyer knows it.

Two sorting rules that matter more than anything else you do:

Never mix grades. A mixed load is paid at or near the bottom grade present. Putting $10 per pound motherboards in the same box as $0.15 power supply boards prices the motherboards at $0.15.

Mixed-grade shipments drop payouts by 18 to 27 percent at refiners, because they have to re-sort before assaying.

One note on CPUs: ceramic beats plastic by a wide margin. Pentium Pro, K6-2 and 386 or 486-era ceramic chips hold up to 0.5 g of gold each, while post-2010 plastic pinless CPUs average 0.1 to 0.2 g. And “pinless” does not mean low value: some high-end server CPUs use ceramic substrates without external pins.

The mistake that destroys the most value

Before any of the above: check whether the item works.

A car ECU is worth $200 to $1,500 as a working module to the reuse market. As a bare board it is $3 to $8 per pound on a unit weighing half a pound to a pound. Opening the case or breaking the tamper seal converts the first number into the second, instantly and permanently.

The same logic applies to anything with a reuse market: server boards, GPUs, industrial controllers, test equipment. The ECU page works through the specific case, and the rule generalises: test first, dismantle only when the reuse route is closed.

Choosing where to sell

Four routes, and the volume that justifies each.

Under 5 kg of mixed boards, no sorting time: a local aggregator. You will be paid near the bottom, but the alternative is spending an afternoon on material worth less than the afternoon.

Under 20 lb and rural: mail-in services are reasonable. You lose $5 to $10 against a local yard and save the trip.

Over 10 kg of identifiable high or mid-grade: a certified refiner with transparent assay reporting and prepaid shipping. This is where the $1.20 to $3.50 rates live.

Two tons or more, with audit requirements: a certified bulk recycler that provides documented chain of custody. This is the server-room decommission case, and the documentation matters as much as the price.

Never ship under 7 kg. Freight and assay overwhelm the payout.

What a refiner actually returns

Useful for setting expectations before you ship, from 2024 to 2025 spot data across twelve North American and EU recyclers.

For each $1,000 of contained value in scrap PCB:

• High grade (server and motherboard mix): $280 to $410 net, after shipping and assay fees
• Mid grade (network cards, GPU risers): $140 to $220
• Low grade (consumer IoT, router boards): $45 to $85

Those figures assume dry, unbroken, sorted lots. Assay verification costs $0.15 to $0.35 per kg, usually waived for repeat shippers above 100 kg a month.

Preparation, in order

Remove steel heatsinks and plastic casings. Heatsinks drop a board from clean-green to mid-grade, which is a swing of about $0.50 a pound for no benefit.

Pull the CPUs and RAM. The single highest-return step available.

Sort by grade into separate boxes. High-grade server, motherboards, mid-grade cards, low-grade consumer, power supply boards.

Skip keyboards, mice and power supplies. They rarely move the needle, and the sorting time is better spent elsewhere.

Do not use solvents, and do not test capacitors. Neither adds value and the first adds risk. Focus on what is visible, weighable and verifiable.

Around the world

The board is the same everywhere; the buyer is not.

Asia Pacific leads in both supply and processing capacity, which means proximity to a refiner is the variable that most changes what you are paid. In markets with formal e-waste infrastructure the graded rates above are achievable. In markets without one, boards move as mixed scrap at the low end regardless of what they contain.

Published national ranges illustrate the spread: general e-scrap runs $0.04 to $101 per pound in the US across all categories, and $0.03 to $1.23 in Canada, with the difference driven by labour costs, recycling infrastructure, regulation and proximity to refiners rather than by the material.

The country pages set out buyer depth market by market, and it is the same variable that decides converter and battery values.

The board value calculator prices your own lot by grade, shows what a general yard would pay for the same material, and what mixing costs.

Questions people actually ask

How much gold is in a circuit board?

A desktop motherboard weighs 300 to 500 g and contains 0.1 to 0.3 g of gold. Boards hold 40 to 800 times more gold than equivalent gold ore, but only a refiner recovers it, and refining costs consume most of the contained value.

Why do buyers pay so little compared to gold spot?

Because acid, labour, safety and waste disposal consume 60 to 80 percent of theoretical value. A pound of ceramic CPUs holds about $650 of gold at March 2026 spot and pays $2.90 to $4.10, and that gap is processing cost rather than margin.

Should I sell boards to a scrap yard?

Only small mixed quantities. Most yards cannot assay boards and pay $0.20 to $0.50 a pound as generic mixed scrap, against $1.20 to $3.50 for verified high-grade material at a proper buyer.

Is it worth removing CPUs and RAM first?

Yes, more than any other step. Stripping RAM and CPUs can raise a lot’s value by over 300 percent, and gold-edge RAM alone reaches $28.35 a pound against $1.25 to $3.15 for the board it sat on.

Which boards are worth most?

High-grade server PCBs at over $10 a pound, then vintage large-socket motherboards at $3.00 to $10.00. Older is generally better, because boards from the 1990s and earlier carry thicker gold plating.

Does mixing grades matter?

Substantially. A mixed load is paid at or near the bottom grade present, and refiners reduce payouts by 18 to 27 percent on mixed-grade shipments because of re-sorting labour. Sort into separate boxes.

Is an ECU worth more whole or as a board?

Whole, by a very wide margin: $200 to $1,500 as a working module against $3 to $8 per pound as a bare board. Opening the case or breaking the tamper seal makes that conversion permanent.

What volume justifies a refiner?

Over 10 kg of identifiable high or mid-grade material, and never ship under 7 kg because freight and assay overwhelm the payout. Assay costs $0.15 to $0.35 per kg, waived for repeat shippers above 100 kg a month.

Are ceramic CPUs really better than plastic ones?

Yes. Ceramic chips from the Pentium Pro, K6-2 and 386 or 486 era hold up to 0.5 g of gold each, while post-2010 plastic pinless CPUs average 0.1 to 0.2 g. Some high-end server CPUs are ceramic without pins, so pinless does not mean low grade.

Prices are from published 2026 buyer sheets and reference services and vary by grade, condition, volume and region. Refiner yield figures are 2024 to 2025 spot data across twelve North American and EU recyclers. Gold content figures are typical rather than guaranteed; a specific lot is priced on assay.
