2011 nickel stamped on penny or dime

Can someone help me please find out what my nickel is stamped on its the size of the dime I think, but it could be on a penny. I need to know where or who to get in contact with to have it checked, anyone interested 

Certainly not a penny (wrong color).  Probably not a dime either. Likely to be a “washing machine” coin.  https://forums.collectors.com/discussion/1033071/washing-machine-coins-are-not-error-coins  Have you weighed it?  Here's mine:

Actually now that I look closer at your picture it appears it's just a shrunken coin.  Size of the lettering is smaller than would be produced by a nickel die.  https://www.capturedlightning.com/frames/shrinkergallery.html

Doesn't look real - could it play money or a token?

Thank you everyone for your feedback, the strange thing about it, is it is metal and most play money is plastic or is of the older nickel. There is no play money of a 2011 nickel that small, that I've been able to find on the Internet. It weighs 4grams exactly. And does not stick to a magnet.  I've looked for costume jewelry, but any coin made for play, costume, or replica is of older money and not of the newer money with no significant value. That's what is strange if you research the Internet you will find nothing like it. At least I haven't, so what to do now??

I believe the answer I gave you is correct.  Did you look at the web site?
