The second one is a 1780 Maria Theresa, heres a site, see which one you have http://www.theresia.name/en/svergleich.html the first one not sure, looks like a restrike
The lower coin is a Maria Theresa thaler and a link I found as well http://en.wikipedia.org/wiki/Maria_Theresa_thaler
Showing only one side of a coin makes it less likely that someone can help but my first impression is that it is not ancient.
This is nothing more than a guess based upon looking at a lot of images but I say the first one is a reproduction/commemorative for either Alexander the Great or his father Philip, more likely Philip. It follows the style of a lot of Macedonian coins with their likenesses. http://artifactsnrelics.craftlaunch.com/ancient/82352648/ancient-greek-coin-sterling-silver-necklace-alexander-the-great-macedonian-chariot/ Look at the center picture. FWIW
