Years on Japanese coinage

Hey guys, I have identified one of my coins as a Japanese Yen
It was minted between 1955 and 1989.
How do I tell when it was minted?

I collect bits and pieces of everything
or should I say I ACCUMULATE!
I also dabble with the darkside image

Ive recently gotten more into currency, especially modern star notes

    There's a little "compare-the-squigglies" chart somewhere in Krause...

    Oh, somebody posted this a while back and I saved it.

    But that's only half the battle, 'cause once you have the date numerals, you still gotta figger out what regnal year or whateveritis to translate it into an A.D. date.

    (Can you tell Japanese coinage is not my forte?)

    Shirohniichan or satootoko ought to be able to contribute something more intelligent.

    If you can't read the date, how do you know that? The only difference between Y#74, Y#95.1 and Y#95.2 is the Emperor's regnal name. The date is under the large "1" on the reverse, and reads from left to right. First 2 characters are either Showa or Heisei. (The first character in Showa has two boxes on its left side, one over the other. The first character in Heisei looks a little bit like a grass rake.) The last character is "nen" (year).

    If there is only one more character the coin is from the Heisei era (1989-present) and the year is either "gan" (first - not shown on Lord M's pink paper) or 2-10. Add the Heisei year to 1988 and you have the western calendar year. Heisei with two date characters are 11-16.

    The number on a Showa coin will be 30-64. Multiply the number before the 10 (that's the plus sign), and add the final number for the Showa year. Then add 1925, and you have the western year.

    OR post, PM or e-mail a picture and I'll date it for you. image

  • I can take credit for the 'pink picture'. I don't mind anyone using it as it's better than violating Krause's copyright by using theirs.
    Here's another one:

    To read the date, for example 51, you will find it written 5, 10, 1. The 51 is the 51st year of the particular emperor's reign, in this case 1976 that would be Hirohito (1926-89). And prior to 1949 the dates were read right to left I believe.

    I thought that might be your "pink picture", Brad, but I couldn't remember.
