What catalyst is common in automobile exhaust?
Generally platinum, sometimes palladium or rhodium, rarely other metals as: Ce, Mn, Fe, Cu, Ni.
How hard is palladium?
This is a partial quote from the Wikipedia, "Palladium, along with platinum, rhodium, ruthenium, iridium and osmium form a group of elements referred to as the platinum group metals (PGMs). Platinum group metals share similar chemical properties, but palladium has the lowest melting point and is the least dense of these precious metals." Please see the related link for more information on palladium. You may want to contact a jeweler for a price per ounce comparision with platinum. You can avoid manually calculating the value of palladium if you have an iPhone or iPod by using an app called Pennyweight. Simply entering the weight and selecting the purity will automatically calculate the value of palladium based on the current market price.

What are the platinum group metals?
The platinum group metals (abbreviated as the PGMs; alternatively, the platinoids, platidises, platinum group, platinum metals, platinum family or platinum group elements (PGEs)) is a term used sometimes to collectively refer to six metallic elements clustered together in the periodic table. These elements are all transition metals, lying in the d-block (groups 8, 9, and 10, periods 5 and 6). The six platinum group metals are ruthenium, rhodium, palladium, osmium, iridium, and platinum. They have similar physical and chemical properties, and tend to occur together in the same mineral deposits
