the only two suppliers in my area that i get from are brinks and garda.
Brinks was pretty hot for me the first 12 boxes of this year(january through mid february) giving me about a 3-4 silver per box average, but since then, i've gotten nothing in the last 20 or so boxes searched, same bank and all.
garda however, is a different story. They suck. I am being straight forward, everybody dumps into garda including some folks who are doing 10+ boxes a week. at least 4 members are on this website that I know of, and probrably more that I don't know of.
I've had several skunk box streaks of 20+ skunks for half dollars, but my worst skunk streak went from august of 2011 to february of 2012 with garda, a 56 box skunk streak at 2 boxes per week. what follows? a box with 12 silvers in it, one of my best boxes ever. Closely followed by that were about 10 or more skunk boxes. recently, silver is making it's way through, but lots and lots of skunks still and my average is way less then 1 silver every 2 boxes, maybe every 3-4 boxes.
you never know when a good box will pop up in the mix...
remember this,
a box of coins is ALWAYS a skunk box until you actually open the box and go through the coins, you never know what the next box may hold.
