I agree that collecting in the main in the USA and in Britain have differing approaches and outcomes. But it might be more optimal to define collecting, as perhaps many "collectors" persay in the USA are actually speculators and not so much collecting for the history, artistry etcetera of a coinage. Myself, I frankly care not about a number assigned to a coin, but only that it has very strong eye appeal to me. I do not need the opinion of another to qualify my own opinion. I own "slabbed" coins, but I did not buy the piece of plastic, but only the coin contained therein. In fact some of the coins I have are undergraded in my opinion, based on my knowledge of the striking history of them. For example: Coin grades lower than most of the cleaned or modified coins you will see available for sale. However PCGS only thinks this qualifies as VF-30 in their opin. However, the dark toning is all original, this coin is not heavily worn, cleaned, retoned, tooled etc. So for me this is much nicer than a coin that grades AU-55 and has the latter conditions. Slabbing are only someone else's opin and should be viewed as such. They are not factual if it does not agree with one's own opin of a piece. Probably my only slabbed British coin, this being a Scottish groat from the reign of David II(1329-1371) this coin grades by the TPG as EF-40. In my opin this is a nice coin, but grading hammered coins is not quite like grading mechanically struck coinages. However for TPG's apparently the same factors are present.
