1970-D Roosevelt Dime w/Proof Reverse?

I received this 1970D Roosevelt dime today at the toll-booth as part of a toll payment. It looks to have been struck with a Proof Die on its reverse. I have read this is a rather rare anomaly. (Maybe I'm seeing things )




The scans abpve are all of the same coin - OBV normal, OBV negative, REV normal and REV negative. The negatives (yellow background) were for emphasis. Even with the heavy circulation wear, would this coin worth anything other than 10¢ (assuming its reverse was actually struck with a Proof Die.)

What makes you think it was struck with a proof die? I don't see any evidence of that in the photos.

 

Sorry, neither do I offhand. Are you thinking that because the reverse of that coin is sharper than the other one?

 

All 4 pictures -scans actually - (above) are of the same coin - One normal and one negative for each (Obverse and Reverse)

Maybe this will help show what i am lacking in my description:

 

I thought all proofs were minted in San Francisco. So why would a proof die be in Denver

 

Good question. Yet, there it be.

Perhaps, someone transporting the dies should not have taken that right-turn at Albuquerque.

Maybe proof dies were used in the production of 1970 'Mint Sets' (not Proof Sets) and reverse was inadvertently left in the press for a portion of the business-strike process? Seems plausible.

 

I'd not heard of this before, but looking at the pics it looks as if it fits the description/photos you reference. That being said, I think you would have to still find someone familiar with that variety and have them confirm it in hand, as opposed to just the pics you post.

 

Here are some more diagnostics for the coin in question

Edit: not seeing the clashes on your coin.

And here is another thread about it, seems some posters think this isn't as common as it seems. I have no clue about it though.

You might want to check it against this, too. And don't forget to look at the other dies known (1 and 3 with buttons on this page) http://varietyvista.com/1970DRDV0023 dime.htm

 

I'm with Camaro and Desert Gem. I see nothing to lead me to think either side was struck with a proof die.

 

Thank you all for your assistance. I visited the Varietyvista website and discovered there are 3 possible Proof design varieties.

Die #3 http://varietyvista.com/1970DRDV0023 dime.htm
This one shows clashes on the Obverse referred to by dsmith23.

Die #2: http://varietyvista.com/1970DRDV0022 dime.htm
This one indicates no die clashes or scratches on the coin whatsoever

Die #1: http://varietyvista.com/1970DRDV0021 dime.htm
This one indicates die scratches through UNUM and Roosevelt's neck

I am of the belief that the coin I have is not the Die #3 variety but falls under either Die #2 or Die #1 varieties - however, with the circulation wear, it is difficult to tell.

In either case, I shall seek assistance and have the coin inspected. Any recommendations?

 

Having looked at the photos...I do see deeper grooves in the flame. I could have been wrong with my initial posting. I am by no means an expert with this series. I didn't see any "general" signs of it being a proof die...but, the die markers very well could be there.

 

Those are not good markers to use for suggestng the reverse was struck with a proof die.
If so, then I have a whole lot of them.

I have a feeling what the presence of those marks suggest is that all proofs will have those marks. But well struck business strikes will also have them. The designs are the same for both dies obviously.

I'll start with the first three I looked at.





Here is a 1970-D of mine. They are there, but not as prominent as the others.



I could be completely wrong. That would not be unheard of.

Keep us posted!

 

There were a lot of strange things going on in those days.

It just wasn't unusual to see coins that appeared to be struck by proof reverse dies.

 

Looks to be FS-1001970D-901
The reverse on these dimes was first used for the 1968 proofs. The design was largely restricted to proof dimes for the next three years, appearing on just a few 1969, 1970 and 1970-D circulation strikes. After 1970 this reverse became the standard for all Roosevelt dimes from all mints through 1980.

 

I think the biggest problem is that even when a coin is an "error", the heavy circulation makes it hard to tell. And "iffy" coins don;t grab a collector very well, so there's not much added value. I do find a few cents from time to time and the best thing to do is put one in a flip, lagel it and collect it myself. They do make good conversation pieces and your investment is only 10c. Really, the people who collect the errors want really good condition coins so it's easily seen.

Just sayin'

 

@ Shrake: That is good information there. Thank you.

@ 10Gary22: I fully understand what you mean. Unfortunately most of the coins (and FRNs for that matter) that usually come across my hands are used and abused. It is difficult to tell from a photo what is and what isn't collectible or valuable. I've never seen a 1909-SVDB Lincoln Cent, except in a photo, yet I know they are collectible and valuable. I can assure you that the coins I have are very easy to discern which die was used.

Oh, In case anyone cares, I just received today a 1970-P with same 'Proof-Like' REVERSE (from 1968) and another 1970-D with the 'Normal' REVERSE. So it does seem like there were multiple reverse die designs utilized in 1970.

Well, I'm glad you posted here, as that's something new I can look for.

 

gbroke, I would think yours does not fit the CPG description of "deep" grooves, at least from what I can deduce ...

Picked this one up at the LCS today for in the "junk" clad bin for $1 (thankfully it's in much better shape than the others I've found)

 

not a proof
