The scoring system differs between the Nintendo GameCube and New Play Control! versions. In the original, the scores are divided into four zones: bronze, silver, gold, and platinum. In the remake, there are only three zones, and each Crest is platinum. In the original version, by obtaining a Crest, Donkey Kong automatically also receives teh Crests from a lower rank as well (e.g. a Gold Crest also rewards him with the Silver and the Bronze Crest).
