Error coins happen every year and mint mark. There is no knowledge of one coin, they happen differently on any coin. Depending on what you are calling an error.
Die cracks/chips/breaks eventually Cuds happen on dies. These are common place, but Cuds are more desirable.
Double struck/chain strikes/machine doubled/doubled dies all can happen. Some are more common than others and worth little extra, others are worth more.
So they question's answer is: "It depends."
