Again,
THANK YOU.
The notion of small sample size, statistical irrelevance, and the tendency for anecdotal information to mislead is lost on many.
Some folks will compare five or six sales,
looking at slab numbers only, and draw far-reaching conclusions. What might be happening in one time and place, and one series / denomination, is not to be wildly extrapolated around the world.
Just because you
think you have a correlation for Frankies doesn't mean it works for Chain cents !
What's more, most people buy the coin, not the slab. That's one reason there's so much standard deviation... not all MS63s are created equal ! Exceptional coins within a grade sell for more.
