IDDD RPMs
____________________________________________________________________________________________
IDDD has purchased John Bordner's original specimen 1974 D RPM-001 discovery coin.
MR Bordner led the research to the Eisenhower D/D Repunched mint mark. We will all Miss him.
"It was the summer of 2009 the Ike RPM Research".
In the early part of 2009, I was made aware of an Ike RPM other than the 71-S/S that is featured in the Cherry-Picker's Guide. This "New" Ike RPM was attributed by John Bordner as a 1971-D/D WRPM-001 and discovered by Tom K. now listed as RPM-1, this raised a big question in my head: Why are there multiple RPM's in other series, but not with the Ike's? To me, that seemed unreasonable. Since I teach and have the summers off, I decided to embark on a massive RPM search operation during the upcoming summer of 2009.
Armed with a reading lamp and an older model stereo micro-scope I had picked up
as a floor-model special discount at the end of a FUN show years back, I sat at
a table for 2 months looking at every mint-marked Ike I could get my hands
on. After all the dust had settled, I had the following "New"
RPM Ike's attributed by John Bordner to add to the list:
1971-D/D WRPM-002 RDV-006
1971-D/D WRPM-003 RDV-006
1973-D/D WRPM-001
1973-D/D WRPM-002
1974-D/D WRPM-002
1976-D/D Type 1 WRPM-001
I sent these (and many other RPM hopefuls) to the RPM "expert," John
Bordner. He was very helpful in not only attributing these RPM's, but
also educating me on things that could cause mint-marks to "look"
like RPM's. Things such as distorted doubling, deterioration doubling, and
ejection die doubling and MDD can all produce mint-marks that look very much
like RPM's.
These RPM's were hardly just dropping out of thin air. Literally
thousands of Ike's were gone through that summer. Yet, only a
handful of examples of each RPM were found. A few months later, another
RPM surfaced, another 71-D/D popped up that didn't match any of the
previous (3) and is now designated as the 71-D/D WRPM-004.
All of these "New" Ike RPM discoveries still leave us with a few
questions: Why are there no RPM's for 1972? Other than the 71-S/S
WRPM-001, why are there no other RPM "Blue" Ike's?
Why do RPM's seem to cease to exist in Ikes from 1972 and 1977 - 1978? more
research needs to be done in these areas. What will be the next
"New" Ike RPM and who will discover it?
Happy Hunting!
Brian Vaile.
