只见它们的正面都印有它们的面值、出产日期、出产地、面值拼音，而背面，它们又分别印有菊花、荷花、兰花。1元硬币上的尽情绽入的菊花让我想起了它“荷尽已擎雨盖，菊残犹有傲霜枝”的不屈不饶！5角硬币上的荷花让我想起了在夏日炎炎，“出淤泥而不染”的荷花亭亭玉立地绽放在池中；1角硬币上的兰花让我想起了在空山幽谷之中，兰花用它哪缕缕清香及娇嫩的身体默默地奉献着它的美丽……，就好似那些淡泊名利，默默奉献的人……。

老师把1角硬币往地上掷去，发出了“叮铃铃”声音，这欢快、悦耳、清脆的声音使我仿佛听到了上课铃声，便油然而生一种紧迫感，想着要赶回教室上课了；又仿佛听到下课铃声，一种舒坦、放松的心情赶上心头，想着终于可以休息休息了。

老师又把一枚5角硬币往地上掷去，发出了“滴嗒嗒”的声音，这沉重、厚作文重的声音，使我仿佛听到了一个男人穿着靴子踩在地上发出沉重的声音；又仿佛听到了水一滴、两滴……滴下的声音，感受着时间一分一秒在间隙中流逝……。

老师随意择起一枚硬币往地上掷去，只听：似清脆欢快、悦耳，又似沉重、有着厚重的分量；硬币的转速已相当缓慢，我仍举棋不定、难以抉择，最后在同学的倒数五秒的叫喊中，我吞吞吐吐地说：“1角！”老师和同学们发出一片叹息声，让我不免有些失望。在随后的第二次猜硬币时，清脆、欢快、悦耳的声音一传开，我就斩钉截铁道：“1角！”这次我果然猜中了，虽然只猜中了一次硬币，我心中仍然充满成功的喜悦！
