not too sure what your asking sorry.. I have been acumulating silver for several yrs now..my first purchase @ 9$oz..Just my 100oz bars i bought in 07 I paid around 13$ US a piece so as you can see..not many banks out there paying that kind of interest.
if you are planning on buying physical then I would just advise you do some research and listen to the likes of Richard Russel,Jim Rogers,Peter Schiff,Gerald Celente,Ron Paul, Marc Faber just to name few...Good luck and for mine this is more about retaining purchasing power rather than making 'Profits'
Paper money is losing value against REAL currency being gold/silver IMO...something not witnessed in such proportions in a long time so ithink it will take some time before mainstream cotton on what is happening by which time it will be over..Just IMO only!!!
