How to make a card slideshow
- Photograph each card flat on a plain surface, straight down, with all four corners in the shot.
- Add the photos above. The tool crops and straightens each card and measures its front borders.
- Type the card name for each slide and reorder the cards with the arrows.
- Edit the opening and closing slides, pick a theme and choose whether to show centering.
- Download the slides as a ZIP, share them straight to an app on your phone, or record a video.
Slideshow ideas that collectors post
- Pack opening pulls. Lead with the set name and save the best hit for the last card.
- Should I grade these? Show the centering on each card and ask viewers to pick.
- Grading submission. Post what you are sending to PSA, CGC or TAG, then follow up with the grades.
- Binder tour. Walk through a set or a personal collection one favorite at a time.
Reading the centering on a slide
The number on each slide is the front centering on the worse axis, measured across the full length of each border after the photo is straightened. PSA's published front limit for a Gem Mint 10 is about 55/45, and a PSA 9 allows about 60/40. A slide only shows the front, so the back can still hold a card back, and corners, edges and surface count as much as centering. For front and back together, use the card centering calculator or read PSA 10 centering requirements.
Before you post a grading pick
Centering tells you whether a top grade is possible. To see whether grading pays, run the card through the is my card worth grading calculator. A Binder AI scan estimates all four subgrades and pulls recent sold prices from the same photos.
