A NEWLY ATTRIBUTED IKE RPM 1971 D/D

[robEzerman]

Guys, HOT NEWS!!

Ike Club Member Tom (TKO-5) just told me a 1971-D Ike he submitted to John Bordner (NCADD President and their MM attributor) received "1971-D WRPM-001" attribution.

CONGRATULATIONS, TOM!!!

The Doubled-D has a large upper left notch (Northwest corner of the D), see preliminary pictures below.



Let's all keep our eyes peeled for this newly discovered Ike DD and the others just waiting to be discovered... Rob

That seems easy enough to see!

Good job on finding this, Tom!

With all the other production problems in 71, there must be more RPM's to be discovered!

Congratulations Tom!

Good Job Tom,
The split serif on the top left sure looks like a split serif from doubling?
Does any of the underlying letter show clearly with a scope?

A remarkable Find!

Great find!

Congratulations!

Since the mint marks are applied after the die has been prepared, any doubling which shows up is solely due to an RPM.

Machine or ejection doubling would not have clearly distinct serif separation and can usually be used to determine machine doubling from an actual doubled die. Primarily because of when the mint mark is applied.

I don;t think I am expressing myself very clearly but the mint mark is never doubled on a true doubled die coin. It is one of the flags in determining a true doubled die.

Lee, you're correct, but the issue with Tom's Ike is whether the doubling of the D is due to a normal "D" punch punched twice or is it due to a doubled punch?

Soft evidence for this being a doubly punched die is it's apparent scarcity (a doubly punched die would presumably have a one die production but a doubled punch would likely "infect" numerous dies), just thinking out loud. . .

Of course, if a doubled punch was diagnosed early on it would probably be tossed.

Nice find Tom.

[AaronMiller]

I feel the spread is too great to be a doubled punch, and it is a true RPM.

Think through the process of how these are made and I think you'll agree. For a doubled punch, more metal on the punch would be pushed out of the way and the doubling would be most evident on the top of the mint mark and/or very close to the sides of the mint mark letter, as we see on the 74-S. As the doubling becomes more separated, the first impressions would be sheared off.

If one had a punch shaped like a triangle, and turned it 60 degrees and then tried to re-impress the image onto the punch, you would end up with a much smaller hexagon punch, or something close, not a doubled triangle.
