  1. The worlds three top grading companies all offer a restoration service. PCGS call is "Restoration service', NGC call it "Conservation", ANACS call it Conservation and strongly deny its a restoration service. They all claim that they remove harmful contaminate from coins to protect the surface. They all state they do not clean the coins they simply remove surface particles including glue, stains, hazing, dip, corrosion and PVC residue. Here is a before and after picture of a US 5 cent shield nickel from NGC I have been in the industry since I was 10 years old and after over 40 years still heed my grandfathers advice "Never clean a coin, you don't own it you are just a caretaker until it is sold onto another generation". I am not sure how I feel about this. All three companies will (Unlike Mickey Mouse graders like ICG or CGS) spot a cleaned coin, I find it hard to explain the difference between cleaning and conservation to my customers when I don't really understand it myself. Worst still, once they are conserved/restored they are then graded with zero mention of this. This does not seem right to me or am I just old fashioned?
  2. This is a table I use for my customers and myself. It is not 100% perfect between the grades but as good as I can determine. (Sheldon Scale is the 70 point grading scale that was created by American Bill Sheldon) and is what is used in the United States and around the world now.

  3. I have this coin for sale on ebay - http://www.ebay.co.uk/itm/1872-Victoria-Gothic-Florin-CGS-Graded-Slabbed-Davies-dies-3A-3-3-High-Grade-/201807267740?hash=item2efca6879c:g:eBIAAOSwPRlXnCtL 1872 Victoria Florin CGS graded and slabbed 37727 _ FL.V1.1872.01 Top cross does not touch the border beads Davies dies 3A - 3 of 3 The coin it's self is in very good physical condition only one or two small edge knocks and a few very small surface marks on the front. Unfortunately the coin has been previously cleaned removing some of the original toning however it has been authenicated, graded and slabbed by CGS as Cleaned - Very Fine. I think this may have been a higher grade had it not have been cleaned..??? To look at the coin with the naked eye it appears darker than in some of the pics due to the flash and the light scouring that is highlighted but isn't really visible to the eye. Best pics 1,4,7. There is a similar coin on http://www.londoncoins.co.uk/?page=retailv2_details&uin=0011462 The population report suggests that this is the 3rd graded by them having only recently been returned, however not being a cgs member myself I can't verify this. The capsule has also been scuffed on the front as you may be able to see in the pictures, you could probably get it re slabbed at a reduced rate having already been graded but you'd have to check on that.
