I'm here as an disinterested observer, medals and exonumia are my area and slabbing is unlikely to affect these in my lifetime. Thus all of my items are raw but I can see the high end Art Medal market going towards slabbing. There are instances in modern life of a product or service being introduced to fulfill a need that previously had not existed. For example "Next day delivery" and JIT (just in time) warehousing, concepts which replaced the older ideas of pre-planning and stock control. These concepts took hold,in part,because they replaced the requirement for skill and knowledge. To a certain extent TPGs do the same for collectors who either cannot master the complex U.S. points grading system; or are too lazy to do so. And as for investors, it's just a way of listing the product. All this said, I'm interested in one comment: "594 is valued by CGS in VF50 grade at 6,- pounds (= almost worthless as cost of slabbing is 12,- pounds" Yet as shown earlier from the ebay example they're perfectly happy to accept £12 to grade a coin worth £6. Good business sure, but what does it say to the coin community at large? "Give us your money and we'll give you the grade" And just out of interest, just how many countries outside of North America are listed in Krause under the ponderous 70 point system?
