I also collect coins with unusual geometric shapes and coins about math or with mathematicians.
In this page are the coins with diferent geometric shapes that I have, all the others are welcome.
In the page dedicated to coins with mathematicians or about mathematics are the coins that I have.
 So all that you can get which I do not have is welcomed even if those are not in my wanted lists.
