1994-D Washington Quarter Strong Doubling On Both Sides!

Note you are looking at the outside edge of the devices. That is usually Machine Doubling. A doubled die has the devices on a spread in the centers of the devices.

[red]Why does a doubled die look like that? The doubling is on the die because of the hub process not falling exactly over a previous hubbing. Thus the doubling is on the die. What you have is a normal die, with the machine altering the devices right after the strike. The looseness of the machine affects the coins, damaging and removing the contour of the devices. This also happens on a doubled die as well flattening the devices:

Note the date is doubled on this doubled die. But also note the yellow arrows? Those are where the machine altered thess devices right after the strike. Machine Doubling on a coin is usually in a single direction, thus the same direction appears on each of these different coins. But MD does have a hard set rules, like alerting stuff in the same direction:

Note how the MD is not always the same. The looseness is not always the same. A doubled die is consitant because the doubling is on the die, but subject to Machine Doubling alteration. Caused by the machine.

Regardless of how strong/extensive, it is still not a doubled die. A doubled die has the doubling on the die. I've seen a lot stronger MD than on your coin:

To a variety collector, they mean nothing. In fact if I saw MD on a variety coin I considered on buying, I would pass. It is a distraction of the real doubling that is present on the coin. The me it is just damaged devices on the coin. Newbies buy them, but later on they figure out it was not what they thought they were buying. Then they are upset and come here and complain.

Take a look at the doubled dies listed by Variety Vista:

The years on that page without being underlines, do not have any listed by them for those years on the obverses. Pretty much the same on the reverses:

So I save my eyes on those years.

Sadly Machine Doubling adds nothing substantial to the value of the coin--unless the MD is out-of-this world spectacular. But even in the most spectacular cases, net gain won't get you a modest down payment on a used 2006 Ford Focus with 220K miles on it.

@plew, first welcome to CCF. Second, that was a really nice job that you did with the adding color to some pics to emphasize the doubling that you were seeing with the coin in hand. Even though it is only worth face value, you certainly could keep this one as a pretty visible example of MD.

I agree with Spence.
The highlighting you added made it easy to see the areas you were referring to.
