Here's why it's valuable:
* First Appearance: The Scorpion's debut makes this issue a significant milestone for Spider-Man history.
* Popularity: The Scorpion has become a recurring and popular Spider-Man villain, adding to the issue's value.
Determining its worth:
* Condition is EVERYTHING: The condition of your comic book is the most important factor. Tears, creases, water damage, or any imperfections will dramatically lower its value.
* Grading: You'll want to have your comic book professionally graded by a reputable company like CGC (Certified Guaranty Company) or CBCS (Comic Book Certification Service). This provides an objective assessment of its condition and helps determine its market value.
* Market Value: The value of a graded comic book can range significantly depending on its condition. A near-mint or mint condition copy can be worth thousands of dollars. A reprint is unlikely to be worth much.
Where to find value estimates:
* Online Price Guides: Websites like ComicBookRealm.com, GoCollect.com, and eBay's "sold listings" can give you an idea of recent sales prices.
* Comic Book Shops: Local comic book shops with experienced staff can often provide estimates for your comic.
* Professional Grading Services: Companies like CGC and CBCS provide market values for graded comics.
Important Note: If you have a reprint of Amazing Spider-Man #19 from 1962, it's unlikely to be worth much. Reprint comics are often printed to meet demand and typically don't hold the same value as original issues.
Before you take any action with your comic, consider getting it professionally graded to get an accurate value estimate.
