i have no problem telling which bank i got them from, US Bank.
however update, 300$ today and i didnt get a single silver. o well i guess.
the teller today told me that they are now out of halves after i got 1000$ in 3 days. so she is ordering more that will come in next week. we will see what the results are then.
the way i see it large banks have more resources to possibly sort out silver, however the sheer volume of business they do leads me to believe they dont even bother.
simple percentages made off of loans and savings accounts make them all the money they need. also they would have to have someone in a specific position who sorts for silver, which seems unlikely.
