1982 Austrailia 1C,2 whiskers… or not 2 whiskers… thats the question!!

Coppergold

I keep pulling these random coins that have anomalies that I cant explain…. When are we going to get a world coin error/ddo/variety listing website other than coins from canadia? Lol

Anyways, heres what i am talking about… in this photo is what looks like extra whiskers, that only show up on one side.
I looked up online the design for this and i noticed only some of them have it. Made sure when i compared them that they were same date..

Ok these next ones are 3 different types. At least thats what it seems like. One has no extra whiskers, another has some split, and one with them (not mine)




Does anyone know what the deal with this is? If there is one type of design more rare than the other, is it doubled die? I find this to be quiet interesting. Thanks for the help!!
