The Rarity Scale helps to determine the quantity of chips that are known to exist. In some cases, the numbers are known precisely, and in other cases, a consensus was reached based on experience, observations, and the opinions of collectors across the country.
Official CC>CC Grade & Condition Descriptions:
Even though there are 5 official grades, the top three grades (N/SU/A) are mostly used as reference on this site, as this covers approximately 95% of all collected chips.
Never used in games. Square and round edge chips will be as from the manufacturer with absolutely no wear, no dings or nicks, no scratches on surface of the chip or inlay.
Slightly Used: (SU)
Only slight signs of use. Edge still crisp but ever so slightly dulled with very little wear. Cross hatching may show slight wear near edge. Few or no edge nicks. Still retains luster in mold design. Bold hot stamp. Inlays excellent.
Typical chip found in play after months/years of use. Slightly rounded edges. Will have minor defects such as small nicks on edges. Inlays are beginning to show even wear and about half of the cross hatching has worn from the body surface. Hot-stamps have dulled. Beginning to show even wear and may be missing a small amount of foil.
Well Used (W)
Moderate and uniform wear of edge, surface and hot stamp. Noticeable edge nicks and/or surface scratches. No luster in mold design. Cross hatching is nearly worn off. Hot stamp is still readable , but much of the foil is missing.
Edges that were formerly sharp and square are now well worn like bicycle tires. Original hot stamp foil is mostly missing with only the recess visible (may have to hold to the light) Moderate to large chips & nicks. Surface cross hatching barely visible (if at all). Severe scratches to inlay or chip surface. Sever color fading. Partial wear up to half of Chipco design from the edge to the center of the chip. Damage such as cracks, breaks, missing inlay or other chip structure, do not apply to this category.
All of the Grading and descriptions for my chips are based on The Chip Rack, and The Official U.S. Casino Chip Price Guide.
