Such factors as illicit exportation, melting (to produce bullion ... I must
confess to having made a small fortune over the past three years buying-up a
small truckload of the older Canadian "nickels," which are 99.9% pure nickel
... which has greatly appreciated in value over that period) 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?)
