If............. just for only 24 hours.............. everyone on this forum................ had a detector that would only detect targets (including coins) in the 12" to 24" depth strata..................... their 'mindset' (((world))) would be turned up-side-down....... forever. ((( A Indian arrowhead is a light/low-density rock........ nearly the same density as dirt............ and will somewhat 'float' in/on the dirt. Coins are high-density/compressed/forged heavy metal...... with a sink-rate relative to its/their density ))).

Exactly
that's why coins dropped in sand sink until they hit the "hardpan" -- which can be anything from a few inches to a few feet or more "depending"...
I've found coins and rings/jewelry in sand on Lake Michigan beaches (as well as in the water) with PI machines up to nearly 2 ft deep on SEVERAL occasions and it's always at the point of the hardpan at which they rest out of reach of even the best/deepest VLF waterproof machines on the market (ALL of which I've owned/tested/used) at one point or another (and some several times over) over the past 3 decades...
Also - it's at that point at which you don't find/detect ANY coins/rings/etc any deeper either... Once they reach the hard/dense surface of the hardpan = they no longer "sink"...
