Hey guys, this forum has been very informative for me as I am new to coins. I just wanted to ask everyone what the difference is between a regular coin (e.g. in a capsule) as opposed to a coin slab. Why is it that Pandas in coin slabs command such a high premium? And what exactly are the judging criterion for coin slabs. All I know is that the higher the 'MS' value the better. But what determines this value?
