coins, maybe this well help someone. Gold coins $1 = 12.11, $21/2 = 12.22, $ 5 = 12.31 , $ 10 = 12.38, $20 = 12.43... All so on the etrac I have seen where the ID part of the the 12 is not all was the 12 when you got a coin. If you have a high tone and the other two no. are what I go by. Like 12.72 go be the 72. Have any of you seen this??
