in answer to your question coop
i would have to say on just some of them.
from one roll, of the 2015 brick, out of 50pc I would say there was maybe 5 or so? I wasnt really counting them and into the jar they went, as I do not think it is much? because I have seen no pics or descriptions of anything like it on any of the sites I roam so I just figured it was some common anomolly?
I was more just wondering because I have seen the similar thing through out my search of many bricks-mostly circulated- on other coins and dates (cant be quite sure of exacts, just know ive seen it) and figured I would ask to expand my knowledge so I'm not passing something by that maybe I shouldnt be?...kind of like those 94
DDR's that are hopefully still in one of the jars somewhere because I didnt know what they were...at that point in time lol
Thanks again
