“Call of Duty” is a franchise, not a single game. Prices vary wildly by title, condition, and region. To give a meaningful estimate, I need:
| Title | Loose Disc | Complete (Case/Manual) |
|---|---|---|
| CoD 4: Modern Warfare | $8–$15 | $15–$25 |
| MW2 (2009) | $10–$18 | $20–$35 |
| Black Ops 1 | $8–$15 | $15–$25 |
| MW3 / Black Ops II | $10–$20 | $18–$30 |
| Ghosts / Advanced Warfare | $5–$12 | $10–$20 |
