I recently cleared my whole silver collection by using the advanced search with "Silver" in the metal field, and the "In" mark checked for my collection. I cleared every coin in my collection, but I still have exactly 5 oz showing up on my bullion count. See pictures below.


I searched silver using the simple search, and it says that I have 4 coins, none of which are silver, so I don't know why they are showing up as silver. Other than that, I have no silver coins in my collection. Any ideas as to why I have this problem?
Thanks, Nathan
