Here is an interesting coin. Supposedly proof, but what's with all the surface scratches? http://www.ebay.com/itm/1874-Three-...59?pt=Coins_US_Individual&hash=item33843b4cab
Think these old proofs are notorious for scratches and it's acceptable and is one of the factor that determine grade.
Is it just me or is this slab fake? http://www.ebay.com/itm/1879-PCGS-P...d=100010&prg=1076&rk=1&rkt=4&sd=221261810859&
I bet someone has cracked open a holder and replaced a coin or the label at one time or another, but I am not an expert on this so all I can say is I don't know. However, the coin inside is a nice coin.
This one looks like an excellent example of 'buy the coin and not the slab'. I would guess this coin would normally grade about VF30 in my opinion. http://www.ebay.com/itm/1869-Two-Ce...52?pt=Coins_US_Individual&hash=item1e7cb1ed90
The 1879 3 cent nickel slab looks fine to me. The NGC 2 cent piece on the other hand looks overgraded to me. I would't call it any better than a 20.
It is at $203.51 and rising. Only about 4 hours left. No, I am not bidding! http://www.ebay.com/itm/171087942798?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649
Let's say you bought this coin for a good price on eBay. Would you keep it in the slab or crack it and put it in your own holder? It is obviously not graded properly. http://www.ebay.com/itm/1881-THREE-...peiAjwo4ObDsAecuyj5as%3D&orig_cvip=true&rt=nc
Here is another thing I am wondering about .... Why would you send a coin like this to be graded? It is a fairly common date and not particularly valuable in this grade.
Scratches and dings may kill non key date coins, but how does it effect key date coins? Here is a two cent 1864 small motto graded VF details with damage. * The damage is a deep scratch on the reverse right bottom of the coin. Red Book lists this coin at $450 in this grade.
