FYI an "error" is more of a 1 of 1 coin. Where as what you are showing us, we would call a "die state" due to the condition the die is in and can repeat the effects seen on your coin over and over again until the die is retired (changed out with another one). As far as 3 from the same roll, I've had a few runs with cracks and chips up to 8 and 11 in the same rolls...neat to see how the chips/cracks progress from coin to coin.
Great photos by the way...
