I don't know how slabbing got into this thread as that is not what it was about. And I have never even seen a silver strike for sale in a slabbed case, yet. Probably at the Convention there will be some, but you could always buy it and remove it from the slab. As a collector I would not want to spoil any of my collection or duplicates by having them slabbed. However, removing or exchanging cases or coin jacketing a silver strike has nothing whatsoever to do with slabbing.
