Thanks for the link but I think it was a little inconclusive except for this paragraph from one of the links.

"Delivery of Silver (d) The receiver shall not be required to accept any tender varying more than 6% above or below 5,000 troy ounces."
This says to me that the reciever can agree to a payment of different tender or delivery of physical Silver at their discretion....Or have I got this wrong??
cheers
