Question About Proof Dies

[jallengomez]

Are proof dies created from the same master dies and master hubs as the business strike dies? The reason I ask is that tonight I've been searching about 100 1964 pf Cents, and have discovered master doubling. However, I checked a few of my '64 business strikes and have yet to find it.

Nevermind. Obviously I didn't think about that one, what with the WAMs and CAMs.

It is my understanding they should, unless there is a subtle design difference, come from the same master die. I have noticed that sometimes proofs either show more than, or less than known engraving or master die doubling. It could also be a doubled working hub. Post pics...

[jallengomez]

Thanks Jason. I'll get some pics up tomorrow. The doubling is miniscule, but it's there.

Here are the images Jason. Like I said, minor, but I didn't see anything listed as master doubling for '64 proofs. The same splits can be seen on all the letters of the outer devices.

I agree, that's a minor rotational spread. You have multiples? Do they share any markers? I am not sure how many proof '64s I have to check...

[jallengomez]

Jason,

Every single one I checked last night exhibits this same doubling. I have a stack of them, and yes, multiple die pairs. If this isn't showing on any of yours, I'll send you a couple of them.

I have many 1964 proofs with minor notching. I am not aware of a master die issue though.

[jcuve]

If there are different die pairings, I can only speculate that either it's doubled working hub or you have multiple minor DDRs that are similar. With so many '64 DDRs already I am not sure which. Nothing I have on hand has minor notching like the example you posted.

I doubt it's the master die, someone would have probably noted that already.

Hmm, very interresting... I am intrigued to say DD, becaus of how many 64 DDRs there were.... either way, neat
