How do you find out the year and the worth of a zippo that has a x1 Bradford PA on the bottom with a C on it as well?

To determine the year and worth of a Zippo lighter with "X1" and "Bradford PA" on the bottom, you can refer to Zippo's dating system, where "X" indicates the year 2001 and the "1" represents the month of January. The "C" likely indicates a specific design or finish. For valuation, check online marketplaces, collector forums, or Zippo-specific resources to compare similar models' prices, as worth can vary based on condition and rarity.
