I've decided to switch to slabs for my Morgan collection. On a PCGS slab there are four "feet" (for lack of a better word) on one side of the slab. I'm assuming they're there so people can stack the slabs, they also seem to break/crack easily. Anyway, are these supposed to be on the obverse or the reverse side of the coin?
The obverse. When stacked flat they keep them together and prevent them from sliding side to side. I keep mine in PCGS/NGC storage boxes so they are irrelevant. I also haven't had any crack or break off.
