To your highness @dangun } I'm presenting Digital Coin backed by Zinc.

Nice coin — solid request, King @dangun. ⚓ I’ll keep this tight and numeric so you can compare it directly to U.S. dollar-coin production costs.

Summary (short)

Material cost (zinc) per coin: ~$0.038

Estimated unit cost in a typical mass run (100k coins): ~$0.16 per coin

Estimated unit cost in a small run (1k coins): ~$2.10–$3.00 per coin

One-off prototype (single coin made/custom-machined): ~$50–$300 (depends on tooling and finishing)

I used current spot zinc pricing (~$3,188 per metric ton ≈ $3.1886/kg) as the metal-cost basis.

markets.businessinsider.com

How I calculated it (step-by-step)

Assumptions (you described “thick zinc coin, not too small not too big” → I assumed a coin roughly the size of a U.S. dollar coin but a bit thicker):

diameter = 26.5 mm (2.65 cm)

thickness = 3.0 mm (0.30 cm)

zinc density = 7.14 g/cm³ (standard)

1) Volume of the coin (cylinder):

radius = 26.5 mm ÷ 2 = 13.25 mm = 1.325 cm

cross-section area = π × 1.325² = π × 1.755625 ≈ 5.5150 cm²

volume = area × thickness = 5.5150 × 0.30 ≈ 1.6545 cm³

2) Mass of coin:

mass = volume × density = 1.6545 cm³ × 7.14 g/cm³ ≈ 11.81 g

3) Metal cost (zinc) per coin:

zinc price ≈ $3,188 / metric ton = $3.188 / kg (sources above).

markets.businessinsider.com

mass in kg = 11.81 g ÷ 1000 = 0.01181 kg

material cost = 0.01181 kg × $3.188/kg ≈ $0.0377 → round $0.038

Add manufacturing &amp; overhead (typical estimates)

These vary by run-size and finish. I give reasonable industry-style estimates:

Mass production (example: 100,000 coin run)

stamping/pressing + plating/finish per coin: $0.05

finishing (antiquing, edge milling): $0.03

packaging, QA, logistics per coin: $0.02

die/tooling amortized: assume die cost $2,000 → $2,000 / 100,000 = $0.02

Total per coin ≈ $0.038 (material) + $0.05 + $0.03 + $0.02 + $0.02 = $0.16

Small production (example: 1,000 coin run)

same per-coin production items, but die amortization: $2,000 / 1,000 = $2.00

total per coin ≈ $0.038 + $0.05 + $0.03 + $0.02 + $2.00 = ~$2.14

Single prototype (one-off)

CNC/custom machining, manual finishing, artwork &amp; setup, and possibly a custom die or 3D-printed mold: $50–$300+ depending on complexity.

(Material cost in that case is still just ~$0.04 — the rest is setup/labor.)

How that compares with U.S. dollar-coin production

The U.S. Mint’s per-coin production costs for circulating coins vary by denomination and year; dollar-coin production costs historically have been more than a few cents per coin (minting, alloys, and security features matter).

Your mass-run zinc coin at ~$0.16 per coin would be comparable to or cheaper than many specialty alloy/feature coins but costlier than the cheapest circulating pennies in raw per-unit terms — driven mostly by finishing and tooling amortization.

If you want this tuned (I can run it further)

Tell me any one of these and I’ll recompute instantly:

coin diameter or thickness you prefer,

desired run size (e.g., 10k, 50k, 100k, 1M),

whether you want plating or paint, and

your target finish (matte, antiqued, gold-spray, lacquered).

If you want, I’ll recompute for a run of 50,000 coins next and show a direct USD-coin comparison table.
