Doing a baseball/soccer field, I got a loud signal and high numbers. A quick glance made me think it was a soccer memorabilia medallion or a referee's heads-or-tails coin. But at home I washed it off and it turned out to be a local market's "good-for" token, still being used, worth $10! That's what I call "efficient" detecting [finding few, but high-value, items]. Happy Thanksgiving. Count your blessings-you may have more than you thought.
