Stewart: A VERY nice proof 71-S you have there... and Oh! so clean!

 

WoW gem +++!!!!!

 

Buy a BU one and carry it in your pocket for a while.

 

Nice one robec!!!:thumb:

 

That's odd. The toned Ikes in my Dansco look nothing like your (gorgeous!) coin --- the color is much more limited to the rims.

Interesting....

 

Are you referring to the FEZ that the shriners wear?

I'm think you are.

 

I just absolutely Love this thread, Constantly new and beautiful Ike's
I have fun looking at them for different varieties


Terry

 

The Wexler/Crawford/Flynn book has been a great help for me. I think the last edition was published in 2007. Any new discoveries since then?

Chris

 

Chris,
All I can say I "OMG" YES
There have been quite a number of discoveries since that book came out.
There are way too many to list but here is the place on the planet that I consider ground zero for Eisenhower Dollar Research. http://www.ikegroup.org/
Great group of guys that are working hard on this series.
Hope you enjoy. I know that I have never had as much fun with any series of coins as I have with the Ike Series. I have been collecting since the mid 70's


Terry

 

Thanks for the link, Terry.

Wow this was a long thread to read and look through but I am just starting to like these big dollars and this did help. The ike group website is pretty cool and they have a cool grading sections to compare your coins to.

There's the Reverse Die Variety 6 (RDV-006) for the 1971-D's



There's also the Prototype Reverse Design Variety 7 (RDV-007) for the 1971-S Business Strike coins



If you look closely, you'll see it appear to be a combination of the Type 6 Gulf of Mexico with a Type 2 Florida.



BTW, for those that are wondering, Type 4 and Type 5 are the two different BiCentennial reverse types commonly called Type 1 and Type 2 (just to make it really confusing)



There has also been at least one significant 1971-D RPM discovered. It looks like this:



There have been multiple smaller RPM's discovered in the 1971-D's, 1972-D's, 1973-D's, 1974-D's and the 1976-D T1's.

Basically, folks are starting to look more closely at these coins and finding, not only commonalities, but significant differences along with addressing specific die marriages.

There is still a long way to go as the primary participant's in such a venture is not necessarily a group of guys but the general public. The more eye's that are looking at something, the greater the possibility of finding something new and unique.

 

Great info 19Ldys:thumb:

 

Do the rev type apply to the Proof to?? I know are there more type that apply to the 71-79 Proof.here a 1973-S 40% silver.can you post them???

 

The proof reverse types are the same definitions which is how the 1972 Type 2 Business strike came about. It's a business strike coin with a reverse intended for the 1971-S and 1972-S 40% Silver Proof coins. The Type 2 reverse is also used on the 1972-S 40% Silver Business strike coin (blue pack).

The RDV-006 on the 1971-D was also intended as the proof reverse for the 1971-S and 1972-S Cn Nickel proofs which were never produced.
The San Francisco mint has been the producer of all proof set coins since 1968. Any proof dies (or planchet's) that were not of high enough quality, were shipped to the Denver Mint (except of course the obverse die's since these may have already received the S mintmark.......but you never know) and ultimately used in production.

There is hard fast evidence supporting this in the existance of 1969-D through 1972-D "Type B" reverse Washington Quarters. The Type B Washington reverse is the reverse used on the Washington Quarters from 1937 through 1972. These Type B Washington Quarter business strikes are, at the moment, very rare to find but do exists thereby proving the die/planchet shipments to the Denver mint.

Another piece of evidence is the 1974-D Kennedy on a 40% silver planchet as well as 1974-D and 1977-D Ikes on 40% silver planchets.

The 1971-D IKE's also are available minted onto proof planchets so the evidence is overwhelming that the US Mint intended to produce Copper Nickel proofs for the Eisenhower Dollar but due to production constraints, did not and shipped whatever was reserved for the production of these coins, to the Denver Mint.

Now, back to the OP's question.

There could be some very rare IKE's out there that have mismatched OBV and REV dies. One that comes to mind is the 1971-S 40% Silver Proof IKE that has a Type 1 reverse. This is a big ticket coin and it's existance suggests that possibilities abound. But.......only if you know your obverse and reverse Type's and WHAT coins they SHOULD be on.

RDV-001 = 1971-S Proof (extremely rare), 1971, 1971-D, 1972 Type 1 Business Strikes
RDV-002 = 1971-S and 1972-S Silver Proofs, 1972-S Silver Business Strike, 1972 Type 2 Business Strikes.
RDV-003 = 1972 Type 3 Business Strikes, all 1973 strikes (proof and business), all 1974 strikes (proof and business), all 1977 and 1978 Strikes (proof and business)
RDV-004 = All Type 1 BiCentennial strike (proof and business) and the single 1976-S 40% Silver business strike.
RDV-005 = All Type 2 BiCentennial strikes (proof and business)
RDV-006 = 1971-D
RDV-007 = 1971-S Prototype Strike

If you find something that does not match the above, I would advise getting an expert opinion since you may have found a modern day rarity!
