Grading the condition and quality of baseball cards is an important process for collectors. There are several professional third-party grading companies that assign official numerical grades to cards, with the most well known companies being PSA, BGS, SGC. These companies thoroughly examine each card and assign grades on a scale, taking into account the card’s centering, corners, edges and surface. The highest grade a card can receive is Gem Mint 10, while the lowest passing grade is usually around Poor 1.
Before sending cards to be professionally graded, collectors should do some self-examination of each card. This involves carefully checking the centering, which means analyzing if the front image is centered left to right and top to bottom within the borders of the card. Slight off-center strikes will receive lower grades. Corners are also crucial – are they sharply pointed or have they been damaged and rounded? Dinged or creased corners drastically reduce a grade. The edges/sides of cards should be examined under bright light for nicks, scratches or dmg along the perimeter. Inspect the surface under magnification for any flaws like discoloration, specks, scratches or print defects.
A card in pristine condition, often referred to as “Fresh” or “Pack Fresh”, could potentially grade Gem Mint 10. To achieve this pinnacle grade, the card must be absolutely flawless – perfect centering, sharp corners, and clean edges/surface inside and out with no flaws visible even under high magnification. Such a true “10” command an enormous premium and are exceptionally rare for even modern issues. Grades of 9 and 8 are still impressive, but may have very slight defects that prevent the perfect 10 score.
Moving down, a Mint grade of 7 could have decent centering but surface issues like a light scratch. Grades of 6 and 5 descend into the lightly/moderately played categories which exhibit more noticeable flaws that start impacting aesthetics/visual appeal like dulling/whitening edges, rounder corners or off-center strikes. Heavily played grades of 4 and 3 show further deterioration and damage like creases, deep scratches or stains that greatly affect the structural integrity and look of the card.
Anything graded 2 or 1 is in Really Poor or Poor condition – these damaged “commons” are usually only worthwhile to collectors if they feature especially significant players or have other unique characteristics like rare errors. More often than not, heavy played examples are not submitted to professional grading services and instead are just referred to conditionally in personal collections using descriptive terms. Raw ungraded cards can still be valuable to collectors depending on many variables, which is why accurately assessing condition is an essential skill.
After analyzing a card’s condition yourself, the next step is deciding whether to send it for professional grading or keep it raw. More valuable RCs, rare serial numbers, autographs and especially vintage cards are most worthwhile to authenticate and slab in a tamper-proof case to protect from further decline and verify authenticity/grade for future buyers or sale. Common cards or low grades may not be worth the costs when raw condition assessing is sufficient. In any case, thoroughly examining each card and understanding the factors that determine grades is an integral part of organizing a baseball card collection.
