Of course gold can be counterfeited - ask Archimedes. Or look up iron
disulfide (FeS2, known also as iron pyrite or fool's gold) - it'll
require pretty close inspection to be distinguished from actual gold.
And this close inspection will also suffice to distinguish actual money
from counterfeited money, so I don't think there's much sense to what
you're saying, unless I'm misunderstanding it.
Personally, with the rise of biometrics, I'd put my money (pun intended)
on two-tier-authenticated - something you are and something you know -
payment systems taking over for regular money in most day-to-day
transactions.
Cheers,
Ivan.
