There's no way of knowing, but think of it this way:

1980-95 = nearly 15 years, as Mick died in the summer of '95.

50 show/private signing/meet and greet appearances per year X 15 years = 750 appearances

500 autographs signed per appearance X 750 appearances = 375,000 autographs. Remember, in show settings, there was the number signed for the public and then the boatload signed behind the curtain for the promoters who brought him in.

No, Mick may not have done a signing every week, but remember that some of these appearances extended for more than one day over the course of an event. I'm considering each day as a separate "signing" when doing this very loose math.

I think these numbers are actually kind of light, as he certainly made a ton of appearances in the 70's as well. Half a million autographs is not out of the question. Completely mind boggling.
