Card centering cheat sheet

The centering lines six grading companies publish for grades 10 to 5, front and back, on one page: PSA, BGS, CGC, SGC, TAG and ACE. Free to print, post and share. “~” is the company’s own “approximately”; “under” marks ACE’s lines, which exclude the boundary (“less than” or “greater than” a split), so a card exactly on the figure does not meet them. The TAG 6.5 and TAG 5.5 lines and every grade below 5 are on each company’s standards page.

Where does your card land?

The sheet gives the lines; SlabbyPrep measures your card against them. Photograph it, and it checks the centering against every line above, then estimates whether grading is worth each company’s fee, from the prices you give it. Every figure is an estimate; no grade is guaranteed.

Questions

What is on the centering cheat sheet?

The centering lines PSA, BGS, CGC, SGC, TAG and ACE publish for grades 10 to 5 (10, 9.5, 9, 8.5, 8, 7.5, 7, 6, 5), front and back, on one letter-size page, with the date each company’s standard was read (PSA 2026-10-28 · BGS 2026-07-14 · CGC 2026-10-28 · SGC 2026-09-17 · TAG 2026-10-28 · ACE 2026-10-28). The TAG 6.5 and TAG 5.5 lines and every grade below 5 are on each company’s standards page.

Can I print it, post it or put it on my site?

Yes. Print it for a shop counter or a show table, post the image in a thread or a Discord, or embed it with the code on this page. Keep it as it is, with its dates and source line.

How current is it?

The sheet is built from the same standards data as the rest of the site. Each time SlabbyPrep re-reads a company’s standard (the date for each is on the sheet), the sheet is rebuilt and the image at its address is replaced. An embed that loads the image from that address shows the latest version; a copy a site or app stores for itself, or a printed copy, keeps the dates it was made from. Each company’s own page always wins.
