Well ,My wife wants to head for the beach, so I will try again for some copper,silver, or gold coins from a 1700s wreck.She will work on her tan while i will try for some old coins.So far the ACE 250 has been very good to me.Ive found numerous Barber quarters as well as old standing Liberties.Any where between 1883 to 1930s.just hope conditions are more favorable ,having had a big storm the other night.Hope plenty has washed up! Will post what I find later tonight.Thanks Wayne
