American Elements' AE Bullion™ group mints certified high purity Selenium Coins from laboratory certified engineered materials with properties applicable to chemical vapor deposition (CVP) for thin film and laboratory standard impurity levels for short and long term physical possession and to allow for exposure and controlled risk to industrial demand fluctuations reflected in the global selenium price. Coins are manufactured and minted under written SOPs (standard operating procedures) to assure quality and consistency by American Elements' AE Planchet of Ultra High Purity Metal Metals™ custom synthesis and refining group. Besides selenium coins, selenium bars and selenium ingots may be purchased by funds, currency reserves, exchange-traded funds (ETFs), private investors, collectors and hobbyists to take direct physical title and possession of the metal with risk exposure from shortages or chemical/physical technology changes, such as in solar energy, and fuel cell developments, equivalent to movements in the industrial application price of Selenium. American Elements offers bonded short and long term warehouse inventory services for AE Bullion™ coins to investors, funds and collectors who do not wish to take physical custody of the metal or lack secure storage or warehouse capabilities. The lowest possible coin unit price to Selenium melt value ratio is maintained through state of the art mint and die systems and analytically certified rounds (planchet or flan) refined and pressed to exacting purity and weight. We also produce Selenium as rod, pellets, powder, pieces, disc, granules, and wire, as nanoparticles and in compound forms, such as oxide. Selenium Coins may be purchased in bulk or small quantity. Portfolios of different elemental metal coins or bars may also be structured and purchased from the AE Bullion™ group allowing for strategic risk allocation and indexing across a basket of metals.

Etching of Medieval Minting Equipment and Processes Selenium is a Block P, Group 16, Period 4 element. The electronic configuration is [Ar] 3d10 4s2 4p4. In its elemental form selenium's CAS number is 7782-49-2. The selenium atom has a radius of 116.pm and it's Van der Waals radius is 190.pm. Selenium exhibits both photovoltaic action, where light is converted directly into electricity, and photoconductive action, where the electrical resistance decreases with increased illumination. These properties make selenium useful in the production of photocells and exposure meters for photographic use, as well as solar cells. Below its melting point, selenium is a p-type semiconductor and has many uses in electronic and solid-state applications.
