Other dates and varieties in this series
Condition drives price more than any other factor on a coin like this — two examples of the same date can be worth very different amounts depending on wear and authentication.
The value table above is organized by grade for a reason — a coin's condition, not just its date, sets where it lands on that range. If you're not sure how to grade, a seller's photos and description should call it out.
A professionally graded (PCGS/NGC) example carries more certainty than a raw coin, and usually a small premium for it. Both are fine to buy — just factor grading into the price you're comparing.
Prices vary between individual sellers here, not one retailer's price list. Sort by price, check the seller's Metal Points and order history, and message the seller if photos don't show enough detail to grade confidently.
