1964' D nickle. I saw a video on you tube were a whent for big bucks by a buyer in an auction. Said it was a crazy rare error in this make of year. Well I got one. Also said it was used for gym in a machine back in the old days.
You had to put a nickel in the vibrating belt exerciser, back in the old days. Sorry but that is not the crazy rare error. The crazy rare error has a triangle on the portico, not a circle. You have the crazy damage error. It is much more common than the crazy rare error.
Where BoobTube is concerned, discard 90% of the claims as lunacy. Don't believe 99.9999% of the remaining 10%.
