The spike in silver prices will cause a lot of low grade common date material to get melted down. Some don't like this, but I think it is good for the hobby to get rid of excess supply as older collectors depart. Plus when people make money in coins for any reason, it is only good for the hobby.
Precious metals will be attractive for some time until economic direction is more clear. Personally though I dont see silver as being portable enough to be a useful store of value.
