Value of Baseball Player Autographs

Some player’s autographs can be worth thousands of dollars. The most valuable autographs are ones from players long gone, the ones who’s name grace the Baseball Hall of Fame, the ones that broke records, and the ones that are part of baseball history: players like Mickey Mantle, Babe Ruth, Joe DiMaggio, Sandy Koufax, Cy Young, Ty Cobb, Jackie Robinson, Lou Gehrig, Ted Williams… the greats of the game are worth the most. Some players only signed a handful of items and their signatures are extremely valuable. For example, Shoeless Joe Jackson was thought to be illiterate and signed his name to very few things… his signatures go for $20,000 to $100,000 depending on the item.

Modern baseball player’s autographs are usually worth less than players from long ago. Some players that are alive today sign very few things which make their signatures worth more. In recent times baseball card companies started releasing limited numbers of authenticated cards that can be highly sought after by collectors.

Marvel Comic Books Worth

Marvel comic book worth

The Marvel brand began in 1939 when Martin Goodman released “Marvel Comics #1”. Goodman began publishing under the name Timely Publications, then Atlas Comics, before finally using the name Marvel Comics in 1961. The first wildly successful title was Captain America which included the artwork of Jack Kirby. In 1941, when the editor for Marvel left, Martin Goodman hired his wife’s cousin Stanley Lieber (Stan Lee) to be interim editor. Stan Lee would go on to become a legend in the comic book world, ruling Marvel for decades and overseeing the release of highly successful titles such as the Fantastic Four, The Avengers, The Amazing Spider-Man, the Hulk, Thor, Ant-Man, Iron Man, X-Men, Daredevil, Black Panther, Captain Marvel, Silver Surfer, Magneto, Loki, the Green Goblin… so many popular characters.

As the comic book market contracted in the 1980’s Marvel would be sold and resold until Disney bought Marvel for $4 billion dollars in 2009.

Which Marvel comics are the most valuable? The old ones with popular titles. Certain characters are just more popular, and therefore more collectible, than other characters. For example there are more Spider-Man fans than Ant Man fans. Obviously first editions are usually worth the most. Here’s how you look up what your Marvel comics are worth:

How to sell your sports cards

Selling your sports cards on eBay.

Once you’ve mastered pricing your cards using Mavin, here are some tips for eBay so you can actually sell them for that price:

1. Photograph Your Card(s) – High quality pictures of your cards are the most important factor when it comes to selling your cards. If you don’t have enough pictures, or low quality pictures, then buyers will be much less likely to buy from you because they don’t trust the quality of your product. Using an iPhone quality camera in decent lighting will be sufficient. Make sure to post front and back images of your card.

2. List Properly – You don’t want to be caught listing like an amateur. This means you don’t want to add a bunch of filler or flashy text to try and make your listing stand out. You’re more likely to annoy a potential buyer than entice them to buy your card. This means don’t say your card is “limited,” “rare,” or “hard to find,” unless you’re prepared to back that statement up. Similarly, don’t add special characters or all capital letters to your listing to make it jump off the page.

3. Sell Cheapest First – While it is tempting to sell your most valuable cards right off the bat, if you’re brand new to selling on eBay you won’t want to start with these cards. When selling online, your reputation is the most important factor in getting someone to buy your product. If you’re selling a $200 card and don’t have any reviews from previous customers, potential buyers might think you are trying to scam them or don’t trust your service. Start by selling lower value cards and build up a reputation as a quality seller on eBay. This will make it much easier to sell your more valuable cards down the line. When selling these lower valued cards, make sure you ship quickly and charge a fair price. This is the easiest way to get a high rating from your customers.

Why we built a worth app


We (the humble founders henceforth referred to as “we”…) collect a lot of stuff: sports cards of all kinds, coins, stamps, comic books, antiques and other items of significant worth. As a collector, you want to know what your stuff is worth… and not from some ancient paper price guide, but what you could buy or sell it for today if you listed it online. We wanted this. We were tired of doing Google searches and digging into websites to gather information on comparable items. It takes time and it is often difficult to find relevant results. And we were tired of building spreadsheets to record and track all this information we found researching online.

Our goal is to build the largest, most accurate database of pricing information that exists anywhere on the web… and share this technology with people through the best user experience possible. We want to empower collectors everywhere with the tools they need to get fast, accurate estimates of what their collectibles are worth.

Feedback needed! What do you think of Mavin?

When we launched this site, we had one goal in mind: make the best price guide out there. We want Mavin to be the easiest to use, the fastest to use, and the most accurate price guide available to collectors. In order to do that, we rely on the feedback of our users. With that in mind, we strongly encourage you to give our site a hard look and tell us what we could do to improve it. We’ve already had some people tell us they want to be able to sort their cards, want different categories added to the results, and have the ability to save their collection. Thanks to their feedback, we’ve been able to give you a much better product. But to make the best price guide available, we need your best input. So please take a look at our feedback form and tell us what would put us another step above the rest.
