From the certificate that I got together with this coin:

---
This is to certify that the token DISARMAMENT COIN is made of the metal of the R-12 (SS-4) Soviet medium range missiles scrapped under the Soviet-American INF Treaty.

The metal poses no harm for your health. The “coin” is a unique souvenir and cannot be used as currency.

- Soviet Peace Committee

Suprisingly big yet light - I am assuming that it is a re-enforced aluminum alloy.

Weight: 9.0grams
Diameter: 40.13grams
Thickness: 3.09mm

Should I check the levels of radiation from this medal?

That's a great use of the metal from the missles. It's a also a neat looking medal.

Not even if I swallowed it whole?

I want one

Neat. That is really light!

Missile???

No, I have no use for one. But a coin, yes.

Oh man I like that.

I found the 1 ruble = 1 dollar aspect way too funny...

Back in 1988, the USSR Govt valued the ruble at about $1.39 US.

I bet ya it still tickles a geiger counter... if you have access to one take a look and see what it reads.

Funnily enough, there is a site about this

thats just a souvenir by private company.
you can print whatever your fantasy allowes on the certificates
