It's not that Colin - in the slab it looks a bit worn, i.e. EF maximum, but outside it looks not only UNC but most lustre too. It is the same coin though (the tiny scratches and specs in the patina match up). It shows that it's possible to flatter a coin simply by choice of angle of lighting. How can you be sure Nick? The pictures aren't that big (it's one time where "azda size" images would actually help ). I can't make out any scratches at all. As for the toning, the dark patch surrounding GEO is the same on both, but the similar dark patch around REX on the right, doesn't appear on the unslabbed picture (left). Also, there appears to be loads of lustre on the left, but none at all on the right. The only way to completely 'kill' lustre is via scanning, but the slabbed picture must be a photo not a scan. Either way, I wonder at the seller paying £10 to slab a sub-£30 coin - its population rating of 9th out of 9 comes as no surprise at all. What is surprising is that 9 people have bothered to pay CGS to slab a 1929 halfcrown! CGS have made £90 minimum out of that particular exercise. "Nice work if you can get it".
