You'll probably be informed by Ebay, but I found out through Nectar - X8 Nectar Points on Ebay from 20th - 27th November.
You will need to activate it I think.
I've finally come to this conclusion myself (mostly). For years I put $$$ into silver because I thought (and still hope) it had a much greater potential for upside gains over gold. But the collectible silver really burned me. If you think about the premiums for these collectible silver coins, its 300-500%. Compare to certain gold coins premiums at 5-20% over spot, with some potential for numismatic gains. I still like silver, but I rarely buy modern "numismatic" silver coins. I think I'll be long dead when silver finally shoots to da moon . I'll be happy buying gold in the mean time
