PCGS Vs NGC Vs ANACS Slabs... From A Collector's Standpoint

Since I participate in NGC Registry Sets, PCGS and NGC are the ONLY TPG's acceptable to me.
And no coins labeled DETAILS or Genuine.
And no raw coins (okay, there's one exception to this).

Back in the days of film, it was easier to photograph coins in PCGS holders, compared to ANACS or NGC.

The bright white plastic surrounding the coin on the NGC and ANACS holders could fool the light meter in the camera, resulting in poor exposure. You could put a PCGS slab on a gray background and the gray color would show through the transparent plastic surrounding the coin. Sometimes I would put pieces of gray paper on top of the NGC or ANACS slabs to cover up some of the bright white background.

Nowadays, with live view, and instant feedback after each shot, this should not be a problem.

I like PCGS over NGC because they are a little smaller than NGC. I know ANACs is smaller, but I don't like the curved holder.

For me, smaller is better. They need to be big enough to adequately protect the coin, but beyond that they are just taking up too much space.

ICG has always had a nice slab, I also liked SEGS slabs as they have a label that shows on the top of the slab, handy when in a box. My favorite all time slab is still the little white ANACS holders, due to size.

Of course for resale I will pick PCGS, I've always made more $$ with coins in their holders than in any other TPG holder.
