Collectors of
ancient coins tend to prefer coins that are not slabbed, which is why enodia suggests breaking it out.
For a collector of modern coins, they want to get their mirror-like
Morgan dollars slabbed so that it preserved, sans finger prints, for all time. That is not really a concern for someone collecting ancients, and also there is more of a tactile element to ancients, with high relief, and flans that are not perfect circles.
Also, ancients collectors like to see the edge of the coin, that helps in authenticating the coin, and also allows for the collector to judge whether a coin was used in
jewelry. The prongs allow one to see the edge but only to a certain extent.
On the other hand, if you have a coin in a slab, you have a guarantee that, according to a particular expert judgment (from whomever slabbed it), that it is authentic. Not only do you know that guarantee, but anyone else seeing it will be able to know that guarantee. Slabs for ancients are becoming more popular, I think that they are somewhat reassuring to new collectors, including old collectors of modern coins, who are just starting to get into ancients. But, slabbed coins cost a little more, and I assume that the dealer passes on that cost to the buyer.
Neat coin, think about why you want to collect and decide about slabbing for yourself.
