OSAKA--While a 500-yen coin may not go as far as it used to, at least it still weighs the same.

That's the verdict of the annual weight test of coinage, which was held at the Japan Mint in Osaka's Kita Ward on Oct. 21.

The annual event, which began in 1872, was the first to weigh new coins with “Reiwa Gannen” (the first year of Reiwa) incused.

While the name of the era on the coins has changed, the test showed that the shiny new coins weighed the same as their predecessors.

“Even though the era has changed, coins carry the same weight as before,” a mint official said.

Japan Mint started producing the new coins on July 11.

During the test on Oct. 21, officials read off the weight of about 25,000 coins that were minted this year on a scale.

For example, the weight of a 500-yen ($4.60) coin is seven grams. An acceptable margin of error for 1,000 coins is 13 grams.

Almost all the coins passed the test with a zero-gram margin of error.
