There are approximately 77.34 standard Morgan silver dollars in one pound (avoirdupois).
A Morgan dollar weighs 26.73 grams (0.88 troy oz). Since one pound equals 453.59 grams, dividing 453.59 by 26.73 gives ~77.34 coins. Weight varies slightly due to wear or minting differences, but this is the standard calculation for uncirculated specimens.
Key Factors Affecting the Count
- Coin wear: Circulated coins may weigh less (75-77 per pound).
- Alloy composition: 90% silver, 10% copper (standard for all Morgan dollars).
- Measurement system:
- Avoirdupois pound: 453.59g (used above).
- Troy pound: 373.24g (~67 Morgan dollars).
Comparison: Morgan Dollars per Pound by Condition
| Condition | Avg. Weight per Coin | Coins per Avoirdupois Pound | Total Silver Content (oz) |
|---|---|---|---|
| Uncirculated (BU) | 26.73g | 77.34 | 70.61 oz |
| Lightly Circulated | 26.50g | 78.20 | 70.38 oz |
| Heavily Worn | 26.00g | 79.50 | 69.56 oz |
How to Calculate for Your Coins
- Weigh 10 random Morgan dollars together (use a scale with 0.1g precision).
- Divide total weight by 10 to get average weight per coin.
- Divide 453.59 (grams in a pound) by your average weight.
- Example: If 10 coins = 265g → 26.5g avg → ~68.6 coins/lb (troy pound).
Common Mistakes to Avoid
- Confusing troy vs. avoirdupois: Jewelers use troy (12 oz/lb); most scales use avoirdupois (16 oz/lb).
- Ignoring culls: Damaged/cleaned coins may weigh significantly less.
- Assuming all Morgans are equal: 1878-1921 issues have minor weight variations (e.g., 1921 coins are often lighter).
