2000 Silver Proof Coin Question

[Tuebits]

These pictures are from a 2000 silver proof set. They have machine doubling with unusual characteristics. Any thoughts about them?

See bottom of the inside edge of the D,
The Q with a fillin at the inside top,
The line on the nose,
The R with the filled in outside curve,
The tip on the S lower inside curve.

Thanks

I see nothing atypical about this case of machine doubling.

My 2 cents

MMD but maybe be wrong Proof since 1968-S hard hard to find a DDO or a DDR as they are all doubled struck to produce the Cameo affect

[Tuebits]

Okay, because the striking process goes through two strikes, if the first strike causes the machine doubling, then the second causes a filling of the space created by the abnormal first strike. thus causing the doubling.

Okay, seems I read that somewhere but where I can not find. I was hoping one of the experts could provide the reference or confirm the thought.

Any one know of this kind of doubling.

In this specimen it appears that the machine doubling occured on the second (or final) strike. Machine doubling that occurs on the first strike is likely to be obliterated on the second strike.

Mike - is it possible to have machine doubling on the first strike of proof coin since the die stays on the coin's surface?

You are referring to recent proofs in which the die stays in contact with the coin's surface through two strikes (only the ram -- the piston that imparts the striking force -- moves). I would say it is possible. Any operation of this sort can produce the kind of jitter that will leave machine doubling.

Normal or Abynormal

Mr. Diamond, considering what you posted, that the second strike would obliterate the first machine doubling, I reexamined the coin in question, and I find them to be normal size and shape letters. Now if they were machine doubled on the second strike they would have exaggerated shapes. What I'm saying is if you consider the outline of the letters they are the same as if they were not doubled, but are within the confines of the normal boundaries of the letters. With these characteristics I think they were machine doubled on the first strike and reshaped to normal letters during the second strike. Please take another look at the pictures above. The letters are the normal size and outline of letters on state quarters.

I'd value any other opinions on this coin, or my logic.

Thanks

Tuebits.

I've said all I can say, or wish to say, on this matter.
