As you can see the older dice has more of a pronounced design and larger text/line while the newer dice are a bit less so but the cut appears to be slightly deeper also.
Second the edges are pretty clear what is new and old and the dice color between the two is very blatant as the newer one is more of a lighter blue compared to the darker blue of the earlier dice.
Size wise the newer dice are a bit smaller but that is mainly due to the rounded edges. The texture on the newer ones seems more sealed and I hope a bit tougher to resist chipping than my earlier set.
Have you bought any of the new dice? What do you think?
