Air testing war nickels (and some silver) with the E-Trac

Just thought folks would like to see these E-Trac numbers. I tested 33 war nickels and the results varied quite a bit.
1 read 12-14
5 read 12-15
12 read 12-16
10 read 12-17
4 read 12-18
1 read 12-19

I know air testing is biased, but knowing the range these vary by may be helpful. Unfortunately these numbers run directly into pulltab territory.

As long as I was setup to test, I grabbed some other coins too:

Dimes
13-45 -- 7 coins (Barbers and teens Mercs)
13-46 -- 30 coins
13-47 -- 87 coins (only one Barber)
14-45 -- 1 coin (Barber)
14-46 -- 33 coins
14-47 -- 4 coins

Quarters
06-48 -- 1 coin (Washington)
07-48 -- 8 coins
08-48 -- 16 coins
09-48 -- 4 coins (SLQ and Barber)
10-48 -- 1 coin (SLQ)

Halves
03-48 -- 5 coins
05-48 -- 2 coins
07-48 -- 2 coin (Barber)
05-49 -- 1 coin (Barber)
