I don't want to beat a dead horse, but I'm afraid those posted mintage numbers are very dubious. Specifically, I'm talking about 2006 and 2007 mintages (and maybe other dates too).
I know, I know, they come from the Charlton "bible". All I have to go by is the RCM
annual reports. I suspect that's all anybody can know without inside mint information.
One more time (if anybody is listening, or cares), according to the RCM
2007 production of zinc cents: 9,625,000
2007 production of steel cents: 938,270,000
How anyone can then conclude (and publish!)
2007 dated zinc cents: 9,625,000
2007 dated steel cents: 938,270,000
is beyone me.
We know that in the RCM
fiscal year 2007, there were 9,625,000 zinc cents produced. We also know that in the RCM
fiscal year 2007, there were 101,475,000 cents produced bearing the date 2006.
These surely must overlap somewhat. In fact, almost no 2007-dated zinc cents have ever been found in circulation. Further, a mint spokesperson told a CCF member here that the entire 2007-dated run was zinc. That may be incorrect too, but there is not enough information to conclude the mintage splits of date and composition. The reports do not discuss this. They merely present date mintages and composition mintages, separately. And (last time I checked) you can't solve
x + y + z + w = 2 billion
by only knowing x + y and x + z.
