To grade comic books, trusted companies such as the Certified Guaranty Company (CGC) and the Comic Book Certification Service (CBCS) will evaluate comic books, grade them on a 1 to 10 scale, and encapsulate each comic in a rigid plastic frame, called a slab. A grade of 10 is a flawless comic, but that grade is rarely awarded. Collectors pay to have their comics graded to ensure the accurate appraisal of condition of their collectible. These comics will be protected for years to come, and a graded comic will have a higher secondary market value. The obvious negative of getting a comic slabbed is you cannot view the interior pages without breaking the slab, and the risk of damaging the comic in the process.
Many collectors of graded comics want to further protect the plastic slab from getting scratched and place them in bags. BCW Supplies offers graded comic bags made from both polypropylene and Mylar.
Prior to 2016, the slabs from CGC were slightly smaller. BCW’s original Graded Comic Bags (1-BAG-GC-R) are designed to fit the earlier slabs. At the 2016 Emerald City Comic Con, CGC transitioned to using a slightly larger slab. You can tell the difference between the two slabs, as the new, larger slabs are welded all around the slab, whereas the original slabs sealed in the four corners but where not welded close. The slabs offered by CBCS are larger than the earlier CGC slabs as well. Hence BCW offers a new, larger polypropylene bags (1-BAG-GC1-R) for the larger CGC and CBCS slabs.
For collectors that demand Mylar bags, BCW offers 2-mil thick Mylar Graded Comic Book Bags (1-GC-M2).
To protect and organize a large collection of graded comics, BCW carries Graded Comic Book Boxes (1-BX-GCB). These boxes will store 35 to 40 graded comics.
