If you own any bi-metallic or tri-metallic images not shown somewhere within the Library, we would appreciate it if you would e-mail the image to us for inclusion.  You will be given credit for each image used.  Send the obverse and reverse high-resolution images separately as an email attachment, along with as much information as possible including: country, year, composition, and size in millimeters, to the Webmaster. Please, do not send images you do not own.
