The Bullion Production Process
1. **Blank preparation:** Metal strips are rolled to precise thickness, then blanks are punched
2. **Annealing:** Blanks are softened in a controlled atmosphere furnace
3. **Upsetting:** Edges are raised to protect the design area
4. **Striking:** Enormous hydraulic presses imprint the design at pressures exceeding 100 tons
5. **Inspection:** Each coin is visually inspected for defects
6. **Packaging:** Coins are stacked in tubes (20 coins) and packed in sealed boxes
Annual Production
In peak years, the U.S. Mint has produced over 40 million Silver Eagles and several hundred thousand Gold Eagles. Production fluctuates based on demand and available blank supply.
