Hello, I found this really big coin at the flea market. Any idea what it is?
It's about 120mm and 1.25mm thick and it has a large hole. It looks to be a proof.

I thought this may be a fun joke. I hope you enjoyed it. 😁

If you think about it, these CDs really big coins, are just like coins!
They come in many different designs, they all have different minted quanitites, some even come with variations, and of course they are all graded by their condition! These coins may be everywhere now, but in the future they will be expensive numistical items!

You are right. There just as much of a coin as any other token.
I remember years ago a TV programme that mentioned when the discs were
first thought of, there was some debate as to what size the hole in the middle would be.
The chairman of the meeting reached into his pocket, pulled out a coin, and said would
this do? It did, and was accepted.

That story seems to be true, it was a member of the famous dutch Philips company and the coin was
a 10 cent ('dubbeltje') from 1950-1980 (sorry, I don't know how to provide a link to the coin-page)
Thanks. N#734
Open the coin page in a different tab, right-click on the web address at the

Hi Zac, thank you very much for the explanation. But I am unbelieveable stupid,
when it comes to computers.
I am afraid if I try to put a link or something, my entire Numista-thing will vanish…
For me it is already an enormous miracle, that I am typing something here and you
can read it there.
But thanks anyway and I always enjoy your valuable contributions to the forum.
I read about the center hole of the CD in an interview with one of the original developers at Philips' and shared it in a post in an earlier thread.
Neat fit.
Seems to be a pattern strike, photos of another side may help
Or possibly this coin, but the pic is a little bit blur to recognise for sure

…het verkeerde dubbeltje…te nieuw…😜
This coin has only been made in proof since being released into circulation in Japan in October 1982 and the rest of the world a year later. There has been several variations of it since then but in the last 5 years less of them are being made due to the people switching to non physical methods.
Although I did hear the CDs predecessor the vinyl record did have have an unusual increase in use in recent decades after nearly 35 years of little use.
There were earlier proofs struck because in 1978 there was something called the Laserdisc which was much larger than the CD (and could show video) but never gained widespread use in the Americas and Europe. However it did see widespread use in Japan and Southeast Asia well into the 1990s.

I have some of those vinyl coins. I like how they make a melodious sound. But you need a special machine for that.
I love the ones with printed pictures on them.

I have so many of these, they all actually play music on one side which is strange, another had old photos on it.
One I played had the Rolling Stones on it, and another Prince - so maybe its Rockstar coinage?

Thats a possibility.
