Found this 1992 D penny. Looks like the d what punched twice

There is always the remote possibility...... let's see what I'm The Do Pest posts. He's been on a good streak and I'm pullin for him!

I don't know why I'm even going to the trouble to type this, and I wish that the OP would put the photos back up, but I saw the photos and for a while had them up on a second computer screen. The reason that I kept them as long as I did was that the mint mark on this coin was very similar to any RPM you could compare it to. It has a very good case for argument here because of the evidence of the crater effect around the mint mark, which only comes from the mint mark being punched into the die. I'm not trying to be an advocate for anyone here, except maybe myself, as I have a 1992 nickel somewhere that also shows the crater effect and slight misalignment of the mint mark, which has always led me to believe that in the early stages of the mint changing the way that the mint marks were punched, some trading of dies between Philadelphia and Denver took place. I found reference to such once in the mint archives but haven't had the time to find it again.

 

I will not name names, but there are a few of those posting to this thread that have absolutely no knowledge of the subject matter, and should be staying out of the conversation. 'Tis better to remain silent and thought the fool . . .

 

you really should name names and specifics

 

Yea, wkm...punk and wagon are meant for each other. Good rid, good bye and so long to them and their coins.

 

Go ahead.

 

I'll start with you.

And your attitude sucks, too.

 

I gave great explanations on posts 7,9 and 10

 

Opinions, opinions, opinions...are just like...well u know...or maybe u don't!

 

You're barking up the wrong tree, Sparky.

 

You're on the wrong thread. No Sparky here.

 

Wow, I've learned a lot from this post!

 

I'm sick of this piece of snot. Blocked!

 

Good bye.

 

I'm out! Blocked! Oh and I forgot to mention, your only a well known member for your ability to insult others.

 

Speak for yourself, punk. Blocked works both ways.....four ways.

 

Very informative link! Thanks for posting. Now if only the rest of the "error collectors" would read it...
By the way, just what do mint workers smoke for lunch? Salami? Oysters?

 

Variety Vista and Dr. Wiles are assets to the coin collector world without a doubt, but his site needs to be updated. you will read there, that when the Mint started using the single squeeze hubbing process, it "effectively eliminated the doubled die", yet he has at least a hundred doubled die listings of coins minted after that date, and they are still being found on newly minted coins today. He doesn't go as far as to say that there are no RPM's after '88, but in fact says that there are none "known". That says to me that there is always a possibility, and he knows this too.

 

Just guessing from some of the things that have been known to pop out that weren't supposed to, smoking arm-dope on special occasions?

I sure would like the see the pix Hommer saw or that I'm The Do Pest would repost them.

Mint Marks
Mint Marks began being added to U.S. coins starting in 1838. Continuing to this day The Department of Engraving & Design's Die Manufacturing Division located within the Philadelphia Mint has produced nearly all Engravings/Galvanos, Master Hubs, Working Hubs, Master Dies and Working Dies used to produce all U.S coins (In 1996 the Denver Mint also began acting as an auxiliary die production facility when demand requires). Until the mid 1980's all working dies produced at the Philadelphia Mint had the Mint Mark hand punched into each one individually and sent to the various other Mint Branches for distribution with whatever the destination mint's MM letter was.
Sometimes impressing the MM into the working dies required multiple strikes and if there was movement or misalignment in between strikes a RPM could be created and passed on from the Working Die to all coins it was struck by. Beginning around 1965 the Mint Marks were hand punched into the Working Hubs instead of the Working Dies which cut down on the number of RPMs but they were still possible.
Beginning in 1985/86 for Proof Coins and the early 90s for normal Business Strikes the Mint Marks we no longer stamped into the working dies by hand rather engraved directly into the original design/plaster mold for all denominations. Due to this RPMs are not found on coins after about 1991.



The last paragraph here stated why coins after 1990 DO NOT have RPM'S.
The Master die is not a hardened steel, requiring a major amount of force to implement a MM. It is made of a much softer composition, therefore no need to strike it twice, if it was even struck. The mm was probably added by machine.

The only MM that I know of after 1990, that is truly doubled is the 1995 D.
But, this is a DDO, not an RPM. IMO for an RPM to ever show up and be attributed after 1990. The single squeeze process would have to be the culprit.
This would be very difficult because no other device on the coin could show rotation, except the MM. Then and only then would it / or could it, get the attribution. The experts still may call it a DDO, not a RPM.
