Why model year matters for some recyclers
While the calculator doesn’t use year in math, vintage items (pre-1980) sometimes have different alloys. The text field lets you note 2024, 2025, etc. for your own organization.
- 📅 placeholder: “e.g., 2024” helps type digits.
- 🇺🇸 No extra fee based on age, but some collectors prefer knowing era.
