Why do we not have Master Die Doubling on the Reverse?

[makecents]

This may be an ignorant question and I've thought about this more than once, I may have overlooked this but don't see any Master Die Doubling on the reverse. Is this due to something in the minting process that I'm overlooking?

Good question. There is known master die doubling on the reverses of 1909 cents. I believe there are another one or two dates as well, but I can't recall that at this time. It certainly isn't as common, but it does exist.

Easy. Because most of the so-called obverse "master die doubling" is not master die doubling at all. That's why.

The 1909 reverse doubling that I am aware of is considered reduction lathe doubling, not a doubled mastered die. Do you find this in error, Bob?

Thanks Bob!! This would be a combination of me paying attention and not,, I tend to do that. So, for the other question, what would be your educated guess as to why it is not as common?

I was hoping you would chime in. So, if you don't think it will hurt my brain, explain to some extent, which and why, are not master die doubling.

I have never done my own research on this Will. I didn't know it was considered reduction lathe, and by whom, or when this was determined. I do not own enough 1909 coins with the anomaly to do the research. Maybe it is something I will get to in time but until then, I won't agree or disagree with either result.

All of those "master die doublings" on the last 1 or 2 digits of the date are just crappy engraving jobs, and are not from a doubled master die.

Thank you Will! That makes a lot of sense. Those 2's have always bothered me, with their extremely isolated "doubling" and the way they look too. I always thought the other class 8 doubled dies were odd, where they were isolated too, like the "L" of LIBERTY but they look like actual doubling.

Worn equipment maybe???

I have the 1909 that's on CC that was considered a DDR til more research was done. Its graded now. If you search old posts it's on here also

Is this the one CCs 1dr-006??? I can see what looks like MD on the NE edge of the T in UNITED as well as the NW of the A in STATES???

[kloccwork419]

No.. its 1DR-005

[jfines69]

No.. its 1DR-005

Looks like 005 and 006 both... Thanks for the follow up and correction!!!

Bob, this 1992 looks to have MD on obv & rev. First one found by me.
