Possible token [решено]

I acquired this coin a couple of weeks ago and have yet to be able to find any information on it. The question I have is; is the date correct for issue date or is it a modern token .. Any help would be duly appreciated ..

Metal: Brass/bronze
Wt: 4.97gr
Ø: 23.9mm
Legend: пролетарии всех стран соединяйтесь
Proletarians of all countries unite

You have an explanation of what this coin is on this web page. I hope yours is real and not just a modern copy.

There are other denominations in the series, e.g. a 3 kopeks.

Here is my search in Google Images.

Thank you for the link. It identifies the coin as a pattern and states they were made from several different metals. I would take it that the one that I have is one made from brass, as it is definitely not copper.

Again, Thank you ..

It would be a good idea to add it to the Numista catalogue!
