F = Fine (well used - .edge tears, discoloration, etc. Crispness .may have gone.);

UNC(全新) = Uncirculated中譯未流通的、最完.美狀態，指一般新鈔票在未使用前的品質，亦指一些紙質甚佳，四角挺直、紙幣無花無摺痕，富凹凸感，.無破損，鈔票雖經使用但仍像未流通的品質，為鈔票評級.中最佳的。



EF(極美) = Extremely Fine中譯接近完美狀態，指鈔.票只有一摺痕，其他方面如UNC。

VF(上品) = Very Fine中譯非常美好的.狀態，指鈔票有幾道摺痕，但鈔票保持原好，無破損，仍有新鈔的質感。

F(中品)= Fine中譯美好的狀態，.指鈔票已在市面流通一段時間，鈔.票邊沿破損、有污點等，沒有新鈔的質感。

VG(下品) = Very Good中譯非常好的狀態.，指鈔票已舊，有破損、骯髒、針孔等，甚至.變得軟綿綿。

G = Good中譯好的狀.態，指鈔票已變得軟綿綿，鈔票部分破損並違失，非常骯髒，被劃花等，為鈔票評級中最差的.。
