Default Question about metal detecting a sandy river

We have an old river with a lot of history but itís all sand and the river overflowed and it left a lot of sand on this field. My question is would there be any old coins that wouldíve washed on land or are they too heavy and they stay where they are?

Sand is light. Coins probably didn't wash up. Wave action will dislodge them. Worth a try but I wouldn't be hopeful

Not sure where you are located, but .... if you are in a part of the country where there are "boom & bust" cycles (chaparral terrain), then river/beach hunting is normally worthless (for old coins, that is).

The reason is: The sand that you are looking at NOW, is NOT the sand that was there 20 or 30 yrs. ago. It will have been "washed out" (downstream) or silted back-in beaches. After each gully-wash rain event.

Perhaps some mid-west states, where the water-table-level never fluctuates beyond a foot or two in any direction, this isn't the case. But for example, here in CA: The beaches that front creeks and rivers is NOT the same "beach" that was there 20 or 30 yrs. ago. Thus .... no matter how colorful the usage/recreational history might have been .... it doesn't pork out old coins.
