The heat theory for the bubbles is not correct. John Wexler was on a tour of the Philly mint and they always thought that heat was involved with the striking process. But he saw one struck and it was not even warm. (which surprised him) This changed his mind on that theory. The rough texture on the coins at first was called orange rind, but it is plating over dust particles from the zinc planchets. Thus a rinsing process prevented this from happening.later on. The bubble are able to be flattened with a toothpick. So they are not a die issue, but a planchet issue. They are not a
Cud as mentioned. A
Cud involves part of the die breaking off the rim of the coin.

So there is no premium attached to your coin. Also the coin is a 1982-D cent.
