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.

CardMavin.com – For what your sports cards are worth

Chances are you found mavin.io through our sister site, cardmavin.com. A lot of users have asked us why we have two sites, so here goes: cardmavin.com is where the majority of our content will live. We wanted that to be the first place people go so that way they understand how to use our price guide most effectively and find some helpful resources about collecting.

Many people who stumble upon our Card Mavin site are just trying to get an accurate price for their old cards that they discovered in their basement. They need the most help when it comes to searching effectively, using the card lingo, and what to do next once they’ve found the price of their cards.

Mavin.io, on the other hand, functions as the mainline to the information that serious collectors need to access. We’ve removed the clutter and try to give you the cleanest interface so you can get the prices you want quickly and efficiently. We will still provide some resources here on this page, but for the most part Mavin.io is the barebones, to-the-point price guide that gives you market values in a flash.

Mavin.io – See what your stuff is worth

See what your sports cards are worth.

The humble team at MavinWorks is proud to launch Mavin.io, a search engine for people to look up what their collectibles are worth. It’s a price guide for all the things people buy, sell, and trade. The process is simple: type in a description of your item, and Mavin will present you with a price estimate based on comparable items. It’s fast and free, just like using Google.

For devoted collectors, a considerable amount of time goes into evaluating an item’s worth and the current online resources do not meet the demand of frequent collectors. However, this problem extends beyond the committed collector. With e-commerce growing rapidly, the number of people buying and selling items online is steadily increasing. This creates a market for anyone who wants to know the value of the item they’re buying or selling. Currently, trying to gauge an item’s worth is a time consuming process. It can involve countless craigslist pages, google searches, calculations, and digging deep into niche websites to find comparable items.

Our competitors charge collectors to access their proprietary price guide. However, those traditional guides are often out-of-date and users aren’t exactly sure where the information is coming from. People don’t want to pay for these guides, and they shouldn’t have to. The market is still dominated by these price guides simply because there isn’t a better alternative that is free, easy to use, and accurate like Mavin.

It’s free. Search engines don’t charge you money and neither will Mavin. You shouldn’t have to spend money to know your worth. You don’t have to pay money to use a search engine… you don’t have to pay money to search Mavin for what your stuff is worth.

It’s easy to use. Say goodbye to wasting time searching through niche websites to find comparable prices. Mavin collects all the pricing information you need and makes it accessible through a search box. If you can use Google, you can use Mavin. The information is presented in a friendly, usable way, and it allows users to quickly find what they’re looking for.

It’s accurate. We tell you what your item will ACTUALLY sell for. We base our price estimates on real-world, real-time market data, not proprietary data like other price guides. We give you a price estimate based on what you can realistically expect to buy/sell your item for. With Mavin, you can select comparable items to generate the most accurate price estimate.
