It tells you that the vending machine will accept new 500 yen coins, but not old ones. That's because old 500 coins were susceptible to easy counterfeiting, especially in vending machines.
Today, as a follow-up to Dom's wonderful guide to Japanese coins, let's learn a bit about the history of counterfeit 500 yen coins in Japan.
First, let's take a look at the difference between the old and new 500 yen coins:
letters spelling out "NIPPON" written in tiny font inside the digits, though it takes time to pick them out with the naked eye.
This "new" 500 yen coin came out in late 2000, having been hastily issued by the Japan Mint in response to a social problem that erupted in the late 90's.
(Incidentally, said mint's coin production branch just so happens to be a few minutes' down the street from my house.)
So what was this social problem?
Well, it turns out that the old Japanese coin, by complete chance, was exactly the same size and composed of exactly the same alloy as the Korean 500 won coin. Though the two coins aren't so hard for a person to tell apart, to a machine the only discernable difference between these coins was a slight variation in weight.

This side looks similar, but the pictures on the reverse are very different.
Entrepreneuring young counterfeiters, upon discovering this bit of happenstance, went to work. The fruits of their labor were a very clever, and very illegal, method of extorting cash a little at a time from vending machines across the country. (Read on in part 2!)

Nickel-copper alloy. Cu75%-Ni25% I'd ask which coin you meant, but it's the same for both the 500 won coin (current, I believe) and the old 500 yen coin. I don't know a lot about alloy values, but I would expect it is not particularly valuable. The 500 yen currency has only been issued since the early 80s, so the coin would not be particularly old, either.ReplyDelete
The "old" 500 yen coin you show is actually a new one minted to correct the problem.ReplyDelete
