On the actual question posed, the metals in the coins needs to be cheaper than the value of the coin to avoid people melting them down. If the coins are to represent small amounts like on earth then palladium is probably out. At current prices 5.6 grams of palladium (the mass of a US quarter) is about US$90. Including a small amount in an alloy coin might still be possible though. Ross On Monday, August 30, 2010, Pierre Abbat wrote: > I'm going to write a page about the economy.
