1964 Double Queen, MD Or DD

You are correct to assume this is Machine Doubling, most of the "varieties" on coins and canada that look like this are no where close to legitimate varieties, this is exactly why I am writing my book so that collectors new and old dont get confused anymore, my book will have only genuine doubled die listings.

With that said, 1964 has 2 different doubled dies, both being on the Reverse, the Doubled Bud and the Doubled Branch.

They have an alright premium in higher quality, but its hard to set a price when they are not common, the 1964 doubled bud is becoming fairly scarce, through all the 1 cent coins ive searched (millions) ive never found one and the only example I do have, came from SPP-Ottawa.

They are on ebay but until more collectors actually find them and know about their existance they are kinda just sitting on the back burner for now, I have no doubt the premium will go up sooner than later though.

A little bit of doubling on the head of a fairly modern coin is NOT an example of "hub or matrix doubling". My god, doesn't CaC even look at the definition of what errors and/or varieties actually are and how they bare defined? I would take anything in CaC with a grain of salt.
