There is some ambiguity of what, exactly, a nickel is. Common knowledge tells us it is a metal, but one would rarely refer to an amount of nickel as "a nickel" without qualification--a lump of nickel, or a vein, or an atom. Nickel is ultimately an adjective in this sense--using it as a noun alone is not common in the language and grammar used in Quazie's initial statement.
As thorough as your judgement is, I'm going to have to withdraw points for grammatical terminology:
