I know nobody here has it, but I'm pretty sure it's not half a millimeter in diameter.  Just saying.

Also made of aluminium but weighs 16 grams???????  That's heavier than a silver half crown.

Aha!! they've reversed it.  It's supposed to be 0.55 grams and 16 mm.  Still doesn't explain why its listed as Netherlands East Indies but has the country as Japan though.

What's interesting about the year 2604 is that it's from the Japanese Imperial calendar, literally.

When Japan became an empire, establishing Nanjing and Manshukoku puppet states in China and occupying South East Asia, they used two calendars, the Showa and Imperial calendar. The Showa calendar, I'm sure we're all familiar with, is based on the enthronement of Hirohito Tenno, and the Imperial calendar was based on Japan becoming a country some 2650 years ago.

An example of this calendar is on this Kusunoki Masashige Festival poster in May 25th, 1931. Notice how the date on the poster says 2591 on the left hand side.



(By the way I collect old posters and Japanese memoribilia. If you have any, I'm definitely willing to trade    )

From what I gather, it was meant to be occupation money during the war.  They took over control of the country, but it was still the original country.  Sort of the same thing as this: https://en.numista.com/catalogue/pieces4711.html

Basically the occupying government wasn't recognized.

Japan once tried to make "New Philippines", liberating the Philippines from the United States. It was popular among the people but not recognized by the Commonwealth

Anyway, I've put in a request for the size and weights to be switched back the way they should be.

That's pretty cool! I always was facinated by antiques, but the only antiques my local antique shop has are
coins and stuff from the '70's and '80's.

70's? That's not even close to antique, although the shops say it is.

Coins, notes, and stamps are just small priceless antiques, so I guess they're enough to satisfy us.
