Rabbit eared coins

[Gunny]

Hello all, have just finished noodling some $1 coins and found a 1984 dollar different to the others I have.  I have 6 different stages of 1984 dollars but this one is very different, the rabbit ears are between what I call stage 3 and stage 4, it has a Spur to the back of the second roo, under the jaw of the top roo and the top of the R of dollar is filled in.  Does anyone else have something similar, as I’m really intrigued by the amount of variations there are.
