Japan's six circulating coins — size, hole and reeding
Japanese coins: the order by size is not the order by value, so the hand reads the hole first, then the reeding, and only then the size

Notes in the source (in Japanese)
大きさの順と、額面の順は一致しない(1 < 50 < 5 < 100 < 10 < 500)。
手で見分ける順は「穴 → ギザ → 大きさ・重さ」。穴があるのは 5 円と 50 円だけで、その 2 つはギザで分かれる。
素材・直径・量目は財務省「通常貨幣一覧」。ギザの数は公表されていない(偽造防止のため。造幣局)。
同じ題材で、見本 300 もある。 こちらは素材・直径・量目と「手で見分ける順」、300 は「価値・大きさ・重さの 3 つの順番が、どれも一致しない」ことを扱う。
