Material Design

• The new half-dollar will be cobalt
• Cobalt has to its low market price per kilogram
  (1 pound0.45 kilograms) (US .07/kilogram as of
  2007). It is also fairly abundant because it is
  found in conjunction naturally with zinc which is
  inexpensive and mined on a massive scale.

To Prevent Counterfeiting

• These measures will be taken to avoid counterfeit
• Fine details using highly expensive machines that
  are only available to the buildings of the United
  States Mint. These details are as follows.
• Extreme surface clarity and side lettering that
  says on the side of the coin Carpe Noctum.

4
Rationale

• Due to its low reactivity it will be hard to
  counterfeit. Counterfeiters, unless they have a
  large supply of pure cobalt will have a hard time
  counterfeiting it. They wont be able to make any
  plated versions of the coins.
• Its low market price makes it perfect for
  mass-production

Source

• We will import from Bolivia. Costing us an extra
  2/.45 Kilograms

6
Refining

• Cobalt is refined through the process of
  Pyrometallurgy which smelts the ore so that we
  can separate the cobalt from the cobalt from the
  zinc
• Heat mineral with coke ( C ) or carbon monoxide
  (CO). The carbon and the carbon monoxide are
  formed by the heat.
• It involves treating metals and ores with heat,
  as in a blast furnace. Carbon and Carbon Monoxide
  are used as reducing agents (any process in which
  one or more electrons can be considered as gained
  by a chemical species) in these furnaces.

7
Life expectancy

• Although most coins have a 30-year life
  expectancy, we will need to replace the coins
  every 25 years as a safety precaution against
  counterfeit. So, we will need to produce these
  coins at a rapid pace, but we will need to slowly
  take these coins out about 5 years into producing
  them. The rate of taking away is not known yet.
• Cobalt can be smelted down and the material can
  be used again as soon as the coins are revoked.
  We will encourage.

8
Production

• We will start by having our artists make a
  design.
• Since we have no need to plate our coins, we will
  have no harmful chemicals in them.

9
Size and Symbolism

• The coin will be roughly half an inch in
  diameter.
• The coin will show a 50 cents sign on one side,
  and the face side will have a picture of JTHM,
  along the bottom, in place of, in God we trust
  will be the statement In Nail Bunny We Trust.
• This will encourage teenagers to spend because it
  shows a cultural icon.

Cost Analysis

• The cost of production is fairly cheap looking at
  12.07/.45kilograms
• This includes the location of resources,
  processing, production, and distribution.
