Why are
Cuds worth more? Well I die chip can been seen on all coin after the chip happens. There maybe 500,000 of them if the die chips earlier. If the die chip happens later, maybe 250,000 coins struck with the same one. But a
Die Cud is probably less than 100 as they retire the dies quicker. So with possibly 100 coins compared to 250K-500K die chipped coin examples, you can see which one is going to have a better premium. A
Die Cud can be small:


Or they can be huge:

So the bigger
Cuds will be worth more.
