In terms of turfed parks (hence excluding relicky sites, beach, etc....) : Not only do the hard-core turf hunters probably pass the shallow zinc, but they probably pass all clad (all shallow stuff) entirely. Yes, even clad quarters, dimes, etc.... In their quest for getting only the old coins that tend to be deeper.
I know there's the arguments that:
a) "sometimes old coins can be shallow"
b) "sometimes those new coins could be masking older coins deeper beneath them."
c) "Why pass clad anyhow ? It adds up eventually."
d) "Sometimes a big man's gold ring can read up in the zinc range"
Blah blah blah. Those people think they can have the "best of both worlds" (both the old AND the new). But it never works out like that. Because when you keep stopping to dig the loud "bongs", not only is a large percentage of your day's time now spent digging clad, but your ears become subconsciously tuned to the loud bongs, and you begin missing the whispers. At the end of a turf hunt with those guys, the outcome is predicable: Example: They'll have 1 wheatie, 40 clad, and junk. I'll have 8 or 9 wheaties, 2 or 3 silver, and only 3 or 4 clad (deeper dimes that fooled me).
So it's not always possible to have the best of both worlds. Unless you simply have the liberty to stripmine a park.
