Start with the date, mint mark, weight, and basic design type. Then compare the coin to trusted reference photos before assuming a variety or error. Many apparent doubled letters are machine doubling or strike damage, so the goal is to confirm die markers.
Check high points first, then fields, rims, and color. Original surfaces generally matter more than brightness. Cleaned or polished coins can look shiny but may be less desirable to advanced collectors.
Use price guides only as a starting point. Real value depends on grade, eye appeal, problem-free surfaces, certification, and recent sales for the exact date and variety.
