I've searched exactly 0 Loomis boxes of dimes and got 0 silvers, it all depends on your area. I've searched 126 boxes of dimes this year and found only 52 silvers though.
Loomis dimes are all ive ever searched-beggining last year was awesome was finding min 2/box was doing about 20 boxes a week- then the new 2013 arrived and it all went down hill- ive only searched about 15boxes this year and found 0 ag

just keep stacking, just keep stacking, stacking stacking stacking
Don't have Loomis boxes, however four of my five banks use Garda, the other uses Brinks. So far year-to-date (3/17/14), I've been running 1.4 dimes per box: on 84 boxes so far. Last years avg was 1.6/box.
