Chrysanthemums, sometimes called mums or chrysanths, are flowering plants of the genus Chrysanthemum in the family Asteraceae. They are native to Asia and northeastern Europe.

In Japan, the chrysanthemum is a symbol of the Emperor and the Imperial family. In particular, a "chrysanthemum crest", i.e. a mon of chrysanthemum blossom design, indicates a link to the Emperor; there are more than 150 patterns of this design. The Chrysanthemum Throne is the name given to the position of Japanese Emperor and the throne. The Supreme Order of the Chrysanthemum is a Japanese honor awarded by the Emperor on the advice of the Japanese government.

Numeral 50 above center hole with the year of issue in Kanji below.

Kanji are the adopted logographic Chinese characters that are used in the modern Japanese writing system along with hiragana and katakana.

The date begins with the symbols for the era name Heisei (平成), followed by the era year, and ends with the symbol for year (年).

Y# 101.1 gives the regnal year as 'first' instead of 'one'. From the second year the regnal year is given as a numeral (2,3,4,...) in Japanese numerals, hence catalog nr. Y# 101.2
