Ok I am bored. This question is not about the grading but the presentation. Purely the look. We will agree you buy the coin and not the slab. Once you buy the coin which slab makes a better home for your coin as you admire it? Color, shape, label, prongs etc
I enjoy any PCGS rattler and later green label's but I do have a soft spot for NGC fatty holders. If I would submit any coins for grading to I would choose NGC for their holder.
NGC, they have much better service. PCGS will block you on social media just for using NGC at this point.
Though I do like PCGS's OGH slabs, might have ripped alot on them with my last comments but many people have been having problems with PCGS lately.
For looks and salability pcgs. Love the old ngc slabs too and have had some amazing coins in them. I hate the new ngc slabs just as much personal favorite is the green pcgs and the doily
I like look and the prong holder of the NGC. As far as older slabs, the old fatty and rattler are where its at IMO.
Generally, I find the NGC slabs to have the most eye appeal, for whatever a slab of plastic is worth.
Honestly...honestly...if ANACS could revamp their old small holder (soaps) with the look of the PCGS holder (clear plastic, a nice, clean symmetrical label, plus the label on top you'd have my slab of preference (and probably my business.) But I can't stand the current yellow slabs, and the blue ones don't ever bring any money. I tend to prefer the look of the newer PCGS slabs but value NGC's (mostly) good customer service and grading standards. Plus, most of my Jeffersons are already NGC slabbed, and I submit mostly world coins, et voila there you have where my money goes.
Original black NGC slab (something about a $3000 piece of plastic makes your coin look better ), PCGS Regency slab as my second choice.
I prefer the look of the NGC slabs. I know the optics on the PCGS slabs are good, but they look "cheap" to me. When buying a coin, I don't really care which holder they are in.
PCGS looks better to me. For current holders, the plastic is optically better and I don't like the NGC prongs. The only time the NGC holders may have looked better than PCGS contemporaries is during the earliest generations.
I don't have a strong preference as I don't have that many slabs. But I do like to have a set in the same slab. Right now I have several German Empire 1 Marks coins in slabs. The first several I got were all PCGS so that is what I look for when adding to the set. If I start another slabbed set then I may well go with NGS but I will try to be consistent in holder for the set.
Are both company's slabs made of the same material but just shaped differently or are their compositions only similar in their makeup?
I don't think so. I think today, they are both inert. Some of the older NGC holders, do impart some toning on the coin. I have numerous Morgans in old NGC holders with the same purplish toning along the rims. I can only surmise it's from the holder.
