Went back to the school I've been finding all the nickels at started out using the Cibola and 5.75 coil around the swing set legs and other play ground equipment plus finding a few coins while walking from one place to another ended up with 7 quarters, 9 dimes, 1 nickel (found it in the same hole as one of the quarters) and 10 pennies, total $2.80, then switched to the omega with its stock coil for the more open areas found another 8 quarters, 6 dimes, 6 nickels, 10 pennies ($3.00 total), 1 junk kids ring (id'd like a pull tab/nickel) a button and the back for a stick pin or something, so total for the day was $5.80 for about 4 1/2 hrs hunting.
