Actionable Recommendations
Strategy by Coin Type
- Bullion (American Eagles, Maple Leafs): Use online dealers (Gainesville/JM Bullion). Their sub-4% spreads beat eBay by 1.3% and local shops by 8.2% 1. Always sell during COMEX trading hours (6:00-17:00 EST) for best rates.
- Pre-1965 Commemoratives: Choose auction consignment (APMEX/Heritage). Certified coins achieve 14.3% net premiums versus 4.2% loss in direct sales 2. Minimum viable value: $750 per lot.
- Uncertified Commons: eBay with third-party grading. Raw coins on eBay sell for spot-5.1% versus spot-11.7% at local shops 4. Budget 5% for NGC/PCGS submission.
Risk Mitigation Protocol
- Verification Threshold: Never ship coins without video verification (reduces fraud by 92% vs. mail-only) 6
- Price Locking: Use dealers with guaranteed 24-hour rate holds (available at 3 of 6 major platforms)
- Certification Requirement: For coins valued >$250, obtain NGC/PCGS grading first – increases net returns by 18.3% on average 3
Conclusion
Digital dealers dominate for bullion sales with optimal speed-value balance, while auction houses remain essential for collectibles. Market data confirms that avoiding local shops (except for emergency liquidity needs) preserves 8.2% average value, and third-party certification generates $18.30 net return per $100 face value. Sellers should match platform selection to coin type and timeline requirements using the verification protocols outlined to maximize net proceeds in 2026’s volatile silver market.
