Agree with everyone above. Also, the reason it is on multiple coins is because the die that stamps the coin has a chip in it, a void is left when the chip falls out, and so when the coin is stamped metal flows into the void and takes the shape of whatever the piece was that fell out. The die images are a negative of the picture on that coin so when the metal fills in the negative space it creates a positive image, hence the reason the chip protrudes from the coin instead of being sunk in. Because the die stamps muliple coins rapidly it can take a while before the damged die is caght so there is an unknown number of coins that are produced with the die chip error. If you got that many in the same brand new roll it's because a bunch of the coins were made and stayed grouped together right through the rolling machine. Sorry a little long winded but but hopefully thorough enough to answer all your questions.
