when i was younger - we get spots like that - thought they were done and then would be near by one of them few years later and stop in and bam it would seem like a whole new field
whether you are new or old - if you have good field spots that you hit for a year or 2 and thought you got it all - think again
couple of spots i hit 20 yrs ago (others did too) and we thought were cleaned out - Ive recently been going back to and still pull small spanish and small American coins that others
missed - will get a rare larger coin now and then but most are IHs or smaller - all the bigger stuff is gone but I will take what i can get
i only get excited now over crotals for 2 reasons - #1 - usually means no ones been there or plows did a good turn over and there may be more to find if im getting bells
or #2 - if they are stamped with a makers mark
