Definitely an unusual (and impractical) slab.
I was given this odd slab as a gift and received it in the mail today. There's some info on sampleslabs.com: https://www.sampleslabs.com/dcgs.html, but not much. I see a number of problems with this design, some of which are also noted on sampleslabs.com:
- The feet are molded into the slab, so they can't be removed or folded. This makes it impossible to stack multiple slabs, and also difficult to photograph since you can't lay the slab flat.
- While I like the way the obverse side of the coin 'pops' the coin out so you can see the edge, this feature creates a deep opening on reverse side through which to view and photograph the coin.
- The slab is also really tall.
If you have any DCGS slabs, please post them!
