Just to add to this: I recently purchased 3 slabbed UK coins from the people that I think Kuhli (or another observant American) mentioned before. They have set themselves up as the first seller of slabbed UK coins, and promote themselves by saying that the slabbed bug is just about to come to the UK from the US...So get them cheap while you can! The 3 coins I purchased with an investor customer in mind were: 1826 Plain edge Proof Half Crown PCGS PR63 1898 Half Crown PCGS MS64 1902 Half Crown PCGS MS63 I got them today and I'm not very pleased because: The 1826 Half Crown is a nice coin, but it does not have a plain edge. It's fiddley to see with it being surrounded with plastic, but at the right angle I am able to determine that it does not have a plain edge. Nice coin though so I think I'll probably keep it. The 1898 Half Crown (supposed to be MS64) has the most awful black carbon spot type mark on the truncation and another less severe one on the reverse. It's UNC and lustrious, but there was no mention of the black marks in the listing and the pictures were not good enough to see them. The 1902 Half Crown has unbelievably ugly patchy toning that is not visible in the picture either. I wil probably keep it. So my lesson today is that slabbing is all very well, but if you're going to sell slabbed coins you cannot just list the grade and have done with it. Descriptions of many coins are not complete if they just list the grade. And Slabbed coins are hard to take accurate pictures of. And god alone knows how a coin with horrible black marks Obv and Rev got away with MS64! (unless it happened in the slab, which is perhaps more scary!) And perhaps most importantly; slabbed coins are not always a great investment for people who know nothing about coins. I can imagine lots of people buying coins purely on pictures and PCGS (etc) grade only....Tucking them away and finding when they come to sell them that the coins are less attractive in the eye of a collector than the grade led them to believe.  Any coin investment has to involve someone that knows lots about coins regardless of whether they're slabbed or not. I'm not saying the seller (who shall remain nameless) is dishonest, but I do feel that they are aiming themselves at non experts from the angle that a 'slab with a grade is all you need', and I believe that to be wrong. Also, they seem to be PCGS and NGC authorised...So if they're slabbing the coins themselves that's even more 'hmmmm'.
