Those see-thru plastic Brinks rolls don't produce at all for me. Also, here in Mich they are peppered with Canadian dimes, so you have to tear the rolls open anyway as to not miss silver. ffdSFBayArea said:Out here in the No. Cal, Brinks uses plastic see through wrappers for their coins except for halves... so one can spot a silver easily.. Last week was my first try at searching dimes. It didn't take me long to look go through a box and found 3 silver roosies. The only bad part was that they seem to short change me.. the box was short by 40 cents. 4 rolls were missing a dime.. I found this out by weighing and comparing the rolls.
