Hier nog een beetje info, het is wel in het engels(vast geen probleem) en komt zo van het net af.
MS70 - PERFECT COIN; No imperfections under 20x magnification; full strike; No minting made imperfections; 100% full dynamic luster; no contact marks or hairlines visible under 20x magnification.
MS69 - these coins are coins that exhibit imperfections under magnification higher than 10x; one or 2 imperfections allowed no more; luster and eye appeal must be the same as a MS70
MS68 - must appear perfect under 10x magnification with the exception of a nearly imperceptible scratch, nick or flaw in a non-focal area of the coin.
MS67 - maximum of 2 imperfections under 5x magnification.
MS66 - Intermediate grade where a coin may have MS67 surface preservation but MS65 luster would then qualify for a MS66 grade.
MS65 - Minor imperfections under 5x magnification but not more than 5 or 6; Full strike and full luster; overall pleasing appearance.
MS64 - Intermediate grade where a coin is decidedly better than a MS63 but not deserving of a MS65 grade; usually a coin that looks like an MS65 until inspected under 5x magnification.
MS63 - Noticeable marks without magnification; toning may not be visually appealing; possibly not a full strike.
MS62 - Above average mint state example and should have MS63 qualities except to a lesser degree in so far as surface preservation & mint bloom is concerned; abrasions &/or scratches should not overwhelm the grader.
MS61 - No wear but scratches, abrasions, and other imperfections are evident; dull lustre and unattractive toning; no obvious scratch or gash making such the focus of the coin.
MS60 - No wear but scratches, abrasions, and other imperfections are evident to the naked eye & fairly abundant; dull lustre and unattractive toning; may have one or two major detractions which just fall short of being deemed a damaged nograde.
