I noticed that 40% bags of junk silver have made the top 40 on APMEX. I have been interested in these products for awhile, but it has not worked out. I am interested on what others on this site think. Do you think 40% silver should be on my priority list. So far, I have been detracted due to Mercury and Rossevelt dimes mostly. I can get the 90% dimes at spot much of the time, so I have been passing up on the JFK half dollars. Thanks.
