Many collectors realize that they should protect their cards. Less obvious to them is that the difference between a near-mint card and a gem mint card typically isn’t one big, unlucky event, it’s dozens of small, everyday events that add up over time. If you are treating your collection as an investment or as something you would like to pass on to future generations, the habits listed below aren’t optional. They are the minimal standards you must maintain.
Double-Sleeve Everything Worth Keeping
A single penny sleeve is not going to keep your cards in mint condition. It is not designed to even try. In and of itself, it serves a different primary purpose. With a single penny sleeve you are trying to keep near identical, loose cards from sticking together and to keep air and oil from direct contact with your card. To ensure your cards remain in mint condition through years of handling, the materials you use matter as much as the habit itself. PVC-free, acid-free holders won’t off-gas chemicals onto your cards the way cheaper plastics can over time.
Control the Environment, Not Just the Container
Ensuring the safety of your cards is essential for maintaining their value. People often do things like keep a holographic Pokémon card in a sleeve inside a binder only to allow it to be exposed to sunlight all day. UV light is serious and fades ink very quickly.
Choose Your Binders Carefully
Many collectors also feel that side-loading pages give their collection a clean, professional look. Finally, binders are designed to store their contents long-term, protecting against dust, UV light, and other environmental factors.
Handle High-Value Cards as if They’re Already Graded
The oils present in our skin can lead to permanent staining on matte cardstocks. It isn’t immediate, so many wave it off. But under the right lighting when you go to submit for grading, the fingerprint residue is very apparent and counts against the surface sub-grade.
Clean, dry hands should be the absolute minimum when handling anything valuable. Microfiber gloves aren’t a bad idea to have around for anything you’d ever seriously submit to PSA/BGS/SGC. Handle them by the edges. Don’t touch the face. These feel like overcautions until you’ve watched a card get knocked from potential 10 to an 8 for a reason that was 100% avoidable.
Audit Your Collection’s Real Market Value Quarterly
The prices you see on the market, don’t actually represent what your cards are worth, the sold listings do. What a seller hopes to get and what a buyer actually paid last week are two very different numbers. Go to TCGPlayer, eBay, or other auction sites and enable sold listing filters to get your hands on real transaction data, rather than wishful yarns.
Also, do this quarterly. Pop report data from grading companies lets you know how many cards of a specific type and rate exist, and that number changes as more cards get sent in. More importantly, the number of cards in a specific grade directly affects its value, a card that was particularly scarce in high grade 2 years ago may now have dozens of copies at that level, and the market will follow.
This will help with insurance as well. If your cards have sufficiently appreciated in value, your coverage may no longer ensure replacement. Take photos, keep your receipts and records of recent comparable sales.
Learn to Authenticate Before You Buy Raw
Counterfeiting is good enough that veterans of the hobby get taken in. Before you give your hard-earned cash to someone for an ungraded card, familiarize yourself with the two simple checks: the light test, which exposes whether a card has the expected internal paper layer, and the dot matrix pattern, visible under a jeweler’s loupe, which is different between legitimate prints and modern reprints. Neither is definitive, but both will exclude most of the forgeries out there.
Slabbed cards from reputable companies don’t have this issue, but they come with the price of slabbing. For raw cards, particularly vintage or high-dollar singles, it’s a must.
The difference between a childhood shoebox collection and a functioning one isn’t as wide as you think. It’s a few easy habits exercised from the outset, before the cards take excessive wear.
