How do tides affect gravel /sand beaches? I've been doing some hunting on the Delaware river and had some success. I dug a deep hole for the hell of it as a test at low tide, the next day the was no evidence of the hole, plus I found a coin that I didn't get a signal from the day before. Can older coins (pre 1900) that are 6+ inches move up to signal range with the movement of the tides?
