"GSA (Government Services Administration) Arguably the first group to "slab" coins. During the period when the GSA was processing the 3.4 million silver dollars from the Treasury hoard they separated them into four different groups. Each of these groups was placed into a different style of holder. These are found in one pliofilm and three types of hard plastic slabs. All holdered in approximately 1972."
Most of the coins in these holders where Morgan Dollars from the Carson City Mint, but a few where from other mints, and even fewer where Peace Dollars. However, most of the Peace and "Non-CC" Morgans where placed in the pliofilm, soft-pack. All the coins in these holders where MS60 or above, but none where graded as such.
The example above is graded by NGC.
