How to Calculate Your Copper's Worth

  1. Find the spot price: Check per-pound rates (e.g., $3.50/lb) and convert to ounces ($3.50 ÷ 16 = ~$0.22/oz).
  2. Adjust for purity: 999 fine = 99.9% of spot; multiply by 0.999.
  3. Subtract fees: Deduct 5-15% for dealer margins or refining costs.
  4. Compare buyers: Get quotes from 3+ sources for the best rate.

When to Sell for Maximum Value

  • High-demand periods: Sell during construction booms or tech manufacturing surges.
  • Avoid market dips: Track 3-6 month price trends to spot lows.
  • Bulk sales: Selling 10+ ounces often secures better per-ounce rates.
  • Certification: Provide assay reports to prove 999 purity and boost offers.

Common Mistakes to Avoid

  • Assuming all copper is 999 fine-test with a specific gravity kit or XRF gun.
  • Ignoring weight units: Spot prices are per pound (16 oz), not troy ounce (31.1g).
  • Overlooking shipping costs for online sales-can erase profits on small quantities.
  • Selling to unlicensed buyers-risk of fraud or underpayment.
