They spray copper oxychloride around gardens and orchards(don't forget the Mencozeb) so it may be that the copper leaching from the coins isn't turning into too bad a thing for some of the micro organisms, maybe it's something else that likes the copper and in turn is preyed upon as food by the worms.$1 and $2 coins also have a high copper content and can sometimes be found at depths that no horses ever pushed them down to.
