Re your 605: The problem looks like the same one as that for
commodities in general (and money is, for Marx, a commodity--that
whose use-value is to serve as the form of value). Namely, they are
produced as values (and surplus-values) but a given one may turn out
after all not to be such. Gold may be extracted and formed into
coins; the intention is for it to be the universal equivalent, a
material form ([mis]representation) of social labor, but here too it
may not work out; a coin may fall to the bottom of the sea and never
seen again, for instance. Then the labor producing it was not even
social, not to mention "immediately social."
