Mexico City Coin Shops

Anyone know of any coin shops in Mexico City?  When I was there last year I was unable to locate any and the usually helpful internet didn't come through for me.

You can find several addresses here (the website is in Russian, but I hope you will understand). Almost all the addresses were added by me, after my trip to Central America.

Thank you so much!  I reviewed the website and it will require a little assistance from the native Russian speaker in my house.  Thanks again.
