Reverse die as the hammer die?

[Petespockets55]

I'm aware the the obverse die has usually (always?) been the hammer die in the U.S.
I think I remember posts/comments about the reverse die being the hammer die on some presses or years.
I'm confident someone here has the answer or can add insight.

Thanks in advance. Cliff

ps. This inquiry is in regards to a clad Washington quarter and possible dropped letter(D) on the obverse.
(Definitely not a MM though)

If memory serves, Flying Eagle cents were struck inverted.

The link is fine... That is the way to do it when you do not have written permission to post the pics of some one else... That does look like the size of the Ds on the rev... The edges appear sharp, there does not appear to be any scrapes or damage across the area, I do not see any corresponding damage to the rev and it appears to be incuse... One of the things that I am not sure of is on the full obv pic I can see what would be the center of the D but on the close up I do not... That may be the lighting??? The only way I can think of the obv picking up a grease blob from the rev is if the dies struck with out a planchet in the chamber??? I am not 100% sure but I am leaning toward a struck thro!!!

I'm definitely a beginner but I was thinking the same thing his Jim.
I'm not sure if the term "fallen letter", D in this case, fits for anomaly on the quarter in the link.
But if I understand correctly, grease can fill a device and if it falls out and lands on a planchet or die face prior to being struck can create an incuse anomaly relatively similar to the letter. (Struck through like Jim says).
The extra "D" on the quarter obverse is similar in size and shape to a D on the reverse design.

It seems like for this to have come from a device on the reverse, the obverse die would need to have been the hammer position for gravity to have dropped the "D" into the position where it ended up.

Thanks again for the insight.

If I am reading the info on error ref correctly http://www.error-ref.com/inverted-dioe-installation/ there are no signs that the dies were inverted... So the only way I can think of a struck thru dropped letter, in this case, would be if the letter fell out of the rev die after a strike... Then no planchet fed into the chamber and the obv die picked up the dropped letter and struck the next planchet to come thru... There would be no clash event when spacing between the dies is correct!!!
