Recently
inherited some coins and other pieces and am having a hard time trying to identify 3 of them.
The first one appears to be foreign, possibly from France, and not sure if a coin, medal, etc.


The second one I just don't know. It has a date of 18x4 on the back whereby I can't make out if the x is a 0, 6, or 8.


And finally I have the one pictured below which again, I'm just not sure even where to begin looking.


Any help as to where I can begin looking for what these are or if you could point me in any direction, it would be much appreciated. Thanks for the help!
