The bid/ask spread represents the difference between what a dealer will pay for a coin (bid) and what they sell it for (ask).
How It Works
Bid Price: What a dealer pays to buy your coin Ask Price: What a dealer charges to sell you a coin Spread: The difference (dealer's margin)
Factors Affecting Spreads
Narrow Spreads - Common, liquid coins - Bullion products - High-demand items
Wide Spreads - Rare or unusual coins - Slow-moving inventory - Specialized items
Typical Spreads
- Bullion: 3-8%
- Common date graded coins: 10-20%
- Rare coins: 20-40%+
