I have never seen an unstruck type 1 copper-plated zinc blank. I even asked Jardens to give me one and they gave me a vague answer about why it's not possible.
Oh, they're definitely errors. I consider them striking errors just as those that are struck more than once or off center - they just didn't get struck at all.
Even the ones that did not get put through a stamping press? Even the ones that the mint puts in a package to sell?
Starting about 1 minute they show "blanks" about 1:45 they start talking about the "upset" process / upsetting mill
Yes. If the intention of a blank or planchet is to be struck, and it was not, it is an error. Purposely not striking them still makes them errors.
these are produced by a private company and sold to the mint ready to strike. Ken Potter wrote about them befor, I believe he had bags of them.
Right. It's just that there are very few people who have seen them being made to prove that, and those people sign non-disclosure forms. I would imagine they go to the upset mill and then they are plated, as the upset Mill might leave scratches. I just can't get anybody to confirm it, including Jarden's who would not comment on it
I like that the OP is able to date this Type 2. I would include the date on the flip. As for the Type 1 plated zinc, if it was plated before the rim is put on, there would have to be some available. When you consider the many billions of zinc cents that have been produced the last 35+ years. I will believe that the plating is put on after the rim, until proven otherwise.
A few months ago Coin Op announced on youtube that they were giving blank's to attendees at a coin show. All one had to do was ask for it.
