Ok so there's not much to expect from a standard 10kg weight plate, it's round and heavy and has a one inch hole in the middle. It certainly does the job. However I ordered two lots of York-10Kg-weights-x2 and both sets (4 plates) have an appalling finish: rough surface moulding, chipped black paint, one has started to show signs of surface rust, they look like seconds. I expect much better.
I already have a selection of Golds Gym weights and these are perfect, so there is no excuse from York. I really cannot be bothered with the hassle to return any of these to Amazon, so one day I spruce them up with fresh lick of metal paint.
At £[] on Amazon, for a pair, the best price I could find, but buy at your own risk!
