How to scan Pokémon cards for value: lighting, angles, and holos

The setup

Four things make the difference between a match on the first scan and a retake.

• Surface: a plain, matte surface in a color that contrasts with the card. A dark desk mat for a yellow-bordered Pokémon card, a light one for a dark-bordered card. CardLens crops the card out of the background, and a clean edge helps.
• Light: even light from a window or an overhead lamp. Avoid a single bright point source directly above the card, which puts a hot spot on the surface.
• Framing: the whole card in the frame with a little margin on every side. The scanner reads the collector number at the bottom edge, so do not crop it.
• Angle: the camera straight above the card. A steep angle distorts the text and hides the rarity symbol.

Holos and reverse holos

Foil surfaces reflect the light source back into the lens, and a glare across the artwork or the text is the most common reason a scan needs a retake. Tilt the card, or move the light, a few degrees so the reflection slides off the card. For a reverse holo the foil covers the frame, so the glare tends to land on the collector number; tilt until the number is clear.

The scanner reads the finish from the photo, and a photo where the foil pattern is visible but not blown out gives the cleanest read.

Graded cards in slabs

PSA, BGS, and CGC slabs are glossy plastic, and the label at the top is what the scanner reads first. Lay the slab flat, keep the label in frame and free of glare, and let the scanner read the grade and the card inside. A slab scanned this way is matched as a graded card with its grade recorded, and the sales behind the range show how copies at that grade have been trading.

A card in a penny sleeve scans fine. A card in a thick top loader scans better if you take it out.

How the condition grade and slab reading work

Check the match

Every scan returns the set, collector number, rarity, finish, and language. Compare the collector number on screen with the number in the corner of the card. If they agree, the value range and the eBay sales behind it belong to your printing. If they do not, retake with better light; the number is the one detail that has to be sharp.

Where the number and rarity symbol sit on the card

Scanning a binder

Set up once and keep the setup. Card down, scan, confirm, save, next. A binder page goes by in a couple of minutes, and every card lands in the vault with its printing, condition grade, and value attached. Reopen a card you scanned months ago and its market evidence refreshes, so the vault total stays current.

Japanese cards

Japanese Pokémon cards use their own numbering, like 227/S-P for a promo, and print rarity as letters rather than symbols. The scanner matches them as Japanese printings, and the match names the language so a Japanese card is not priced as the English one. The setup is the same; check that the language on screen matches the card.
