Don't know if this steps the bounds of COC, but I have a source, private seller. actually part of my extended family, they have about 150lbs of silver bars/ coin too, everything from junk to libertys/morgans cool old pennys & paper money, mis-stamped,and gold too
but lots of the 1oz bars.  
I was just over there looking at a large portion of it and was blown away, they could open a coin & pawn with what they have.  they decided they'd like to sell some recently, so If your interested  IM me your info & I'll get it to them
