Such factors as illicit exportation, melting and counterfeiting (to name but
a few of a long
list of likely significant and uncontrolled variables) have plagued all
previous econometrical
attempts at analyses of coinage [lost] in circulation ... few analysts have
even acknowledged
such problems ... e.g., this article gives figures on the current levels of
counterfeit Euros
[and, of course, the stated number of 164,000 counterfeit coins having been
removed from
circulation in 2006 by central banks grossly understates the magnitude of
the problem, and
does not even acknowledge the millions of "undetectable" bogus Euros known
to have
been injected by state-sponsored counterfeiters, viz North Korean) :

Subject: age of coins in circulation
i heard a lecture recently, in which someone mentioned a small experiment,
where he tallied the dates of the coins in the pockets of his acquaintances,
and i was wondering if anyone has seen reference to anything more
systematic? i know philip barker makes reference to the problems of trying
to date the contents of someone's pockets based on the coins he tried to use
to make a phone call, but i was wondering if there might have been a more
systematic study done somewhere, sometime, and not necessarily by
archaeologists (banks or mints, to guage the age of coins in circulation?)
