Here are some problems I see with it, and some proposed modifications.1 white shard = 100 emeralite coins
1 emeralite coin = 100 adamantium coins
1 adamantium coin = 100 platinum coins
1 platinum coin = 100 gold coins
1 gold coin = 100 silver coins
1 silver coin = 100 copper coins
1 copper coin = 10 copper bits
1. First of all, it introduces "materials" that don't exist currently in the game. Why use platinum when we can use Mitrill? Why use copper twice, when we can use iron? How about something more like this?
1 emeralite coin = 100 meteorite coins
1 meteorite coin = 100 adamantium coins
1 adamantium coin = 100 mitrill coins
1 mitrill coin = 100 gold coins
1 gold coin = 100 silver coins
1 silver coin = 100 bronze coins
1 bronze coin = 10 iron bits
This uses all the materials commonly avalible in the realm of metals. It also puts a raw value of each metal compared to each other.
2. Why not make coins and ingots interchangable? Each material could be had in several sized pieces.
1 talon = 10 bars
1 bar = 10 ingots
1 ingot = 10 coins
1 coin = 10 bits
talon 100 pounds
bar 10 pounds
ingot 1 pound
coin 1/10 pound
bit 1/100 pound
In this way you would make it easier to move and store larger quanities of metals. Using the same conversion between metals 1 Talon of Silver would be worth 100 Bronze Talons, or 1000 Bronze Bar. Rarity of mined metals could be adjusted to the same rates. In short, metal suddenly has intrinsic value, and not just value as resource.
3. Construct some kind of "universal bank" that allows the exchanging between metals. If the bank has no silver left, you can't trade in your bronze for silver. If the bank has to bronze left, you can't trade your silver for bronze. If there is not adamantite to be had, the changers aren't going to suddenly create some. In short, market rarity directly effects your ability to exchange.
Bank would take a percentage of "fee" for exchanging between metals, possibly about 20%. This would slowly increase the bank's pool of resources. A smaller fee would be charged for changing between forms of 'bullion' such as from a Talon to 1,000 coins. You might only get 950 coins from your Talon as part of the fee. Once again, that raw metal is added to the banks pool, allowing it to exist.
4. Gems? Where do gems fit in? Current gems are a bit mixed as far as value. Obsidian? Hah! thats a rock not a gem.... I would concider something like this instead?
Blue Diamond, Diamond, Ruby, Emerald, Tanzanite, Sapphire, Garnet, Citrine, Topaz, Opal, Lapis, Beryl, Peridot, Amethyst, Tourmaline, Jet, Spectrolite..... the list goes on....
All these gems are different, and not nessacarily better. In Folklore, Legend, Healing Properties:
Spectrolite brings forth each person's strengths, originality, aids sleep, relate to others.
Lapiz strengthens total awareness, creativity, ESP, skeleton, thyroid, helps to expand viewpoint.
Opal aids inner beauty, faithfulness, and eyesight and helps recall past lives.
Topaz was thought to heal both physical and mental disorders and prevent death during the middle ages. The Greeks believed it had power to increase strength and to make its wearer invisible while the Romans believed it had power to improve eyesight. The Egyptians wore it as an amulet to protect them from injury.
Meteoric iron is used for alignment and balancing; it symbolizes the aptitude and strength required for endurance. Nickel is thought to purify the blood and increase the body's iron content.
Peridot is thought to bring the wearer good luck, peace, and success,. Its powers include health, protection, and sleep. The advantages of peridot are to attract love and calm anger while also soothing nerves and dispelling negative emotions.

Could we not take and somehow make gems actually DIFFERENT from each other instead of just better or worse then each other? Make them have different properties, intrisic abilities, and/or benefits to wearing. Stablize the enchant difference between gems to be much more close.
Anyway, these are some of my thoughts based on the recent topics.
