Trading Card Protection Options Explained

Whether you are new to collecting, returning after a long absence, or a veteran hobbyist, it is important to make sure you keep your cards protected. The sheer array of protection options can be overwhelming, but getting it right can ensure that you maximize both your financial and your emotional investment. The Pennysleever has prepared this guide to explain the most common options and prepare you to confidently identify the right solution for your collection. 

1. Soft Card Sleeves

Soft card sleeves go by many different names: standard card sleeves, penny sleeves, protective sleeves, and many others. But no matter what they are called, these are the foundational pieces for any collector.

Depending on how you collect, you might use soft sleeves alone (when stored in a collector box), or in conjunction with another means of protection, such as a toploader or a semi-rigid card holder (more on these in a moment). A quality soft sleeve should be transparent to the eye, and feel smooth in your hands, with no sticky residue or tacky feel. 

2. Toploaders

Toploaders are the next most commonly used option, and are used in conjunction with a soft card sleeve. Unlike soft sleeves, which can serve cards of a variety of thicknesses, toploaders come in a wide variety of sizes, so it is important to understand the sizing of cards, and to choose the correct size for your card.

Toploaders are made from a more rigid plastic (PVC, to be precise), and offer greater protection than a soft sleeve alone. This is crucial for protecting the corners, edges, and surfaces of a card. Toploaders are also a nicer display for cards, and allow for greater confidence in handling and sharing cards.

If you collect Pokémon or TCG cards, you don’t need to worry about sizing (just look for “standard” sized toploaders, or 35 pt toploaders), but sports card collectors need to be aware of the differences. For example, a thicker chrome autograph card, such as a Bowman Chrome auto, would require a 55 pt toploader, and a relic card might need a 130 pt toploader. 

3. Magnetic Card Holders

Magnetic card holders, like toploaders, come in a wide range of sizes (The Pennysleever has eight sizes, from 35 pt. to 360 pt.). Unlike a toploader, which leaves the top edge of the holder exposed, a magnetic card holder is actually two parts: a thicker “base” into which the card is secured, and a thinner window. The base is notched (to open and close the case), and the “window” has two small hinges to lock into the base, and a small magnet at the top to secure the two pieces together.

One important thing to note about magnetic card holders is that unlike toploaders, the default method of storage is to store your cards unsleeved. There are some magnetic card holders that are designed specifically for use with sleeved cards, but putting a sleeved card into a standard magnetic card holder creates the risk of corner or edge damage.

4. Semi-rigid Card Holders

As the name suggests, semi-rigid card holders fall somewhere between soft sleeves and toploaders on the rigidity scale. Semi-rigids, like toploaders, are designed to be used with soft sleeves, to prevent any scratches to the surface of the card during insertion.

While some collectors, primarily those who collect vintage cards or non-standard sized cards, use them for storage and display, most people will use semi-rigid card holders primarily for submitting cards to a third party grading company like PSA or CGC. Please be aware that some companies are very particular about what size holder to use, and how to pack the cards, so pay close attention to the size. Semi-rigid card holders #1 from The Pennysleever are the proper dimensions for grading submissions of standard cards. 

5. Team Bags

Team bags are transparent sleeves that are often used in tandem with another form of protection, often soft sleeves or toploaders, although they can be used with raw (unsleeved) cards as well. Originally designed to hold around 25-30 cards, about the size of a complete team set of sports cards, these bags are often used to secure a number of cards together, either for mailing or for easy organization. While there is no standard size for team bags, an average team bag can hold about 35 raw cards, about 25 sleeved cards, or about 5-6 toploaded cards.

Often grouped together with team bags are protective sleeves for toploaders, magnetic card holders, or graded cards. While they are similar in design, often having a small lip with a resealable adhesive strip, these sleeves are often designed in a way that provides an aesthetically pleasing tight fit, and are tailored to individual grading companies. A PSA graded card bag, for example, will not protect an SGC graded card. If your collection includes graded cards from different companies, you might want to consider an unfitted, all-purpose bag.

6. Albums, Binders, and Binder Pages

What originally began as a simple nine pocket page, with individual pockets for standard sized cards, to be stored in a three ring binder,  has grown into a wide range of protective options. There are a variety of pocket sizes to accommodate not only standard cards but also tobacco sized cards, postcards, and many other vintage sizes.

A newer variation on this idea are fixed paged binders, the most common of which is a 20 page, double sided nine pocket binder, with a capacity of 360 total cards. However, there are smaller binders that can hold 4 cards to a page (160 total cards), and larger binders which can hold 12 cards (480 card capacity). In addition, there are versions meant to store only sleeved cards, and others that accommodate toploaded cards. In short, there are binders and binder pages for any style of collector. 

As you can see, there are countless ways to protect your cards. The best approach is the one that is most appropriate to your budget, interests, and storage space, so don’t be afraid to try different styles out and see what best suits your individual collector style.
