47 IV 37 · D1a (Quadrupled Right & Doubled Left Stars, Zerbe “Proof” Dies) (189) I-4 R-5

Obverse IV 37– Right stars quadrupled and left stars doubled towards rim as is upper crossbar of second 1. Slightly doubled top edge of cap fold and PLU-BUS towards rim. Die marker– Thin die scratch up to right from left tip of serif of left upright of second U in UNUM. Die used to strike so-called Zerbe “proof” pieces.

Reverse D1a-- Die markers– Extensive die polishing lines within wreath bow and to right and left sides. Prominent horizontal polishing line between eagle’s legs and short double lines on fourth inner feather from bottom of eagle’s left wing next to body. Die used to strike so-called Zerbe “proof” pieces.

Does it have any of the other die markers? Check for the double lines in the eagle's left feather, and the die scratch from the top left of the U in UNUM to the denticles.

Will check when I get home tonight. Seems that I took pics of everything but what I needed.

My son was home and able to get some shots for me.


die gouge pointing to denticles:



left stars on obv..quadrupled


die gouges through tailfeathers....sorry for being upside down didn't catch it.


another small die gouge from U to denticles:

That gouge on the U looks very promising! Same position and angle as the VAM 47.

Try to compare it to the pictures on the ashmore site....

Looks like mine is a later or earlier die state. There is no horizontal line between the legs but on the wing there is a bit of the die gouge to the far right and you can see the identical vertical gouge in the vam guide pics as this one.

Looking at Leroy's monograph on the subject, the die polishing lines Norm shows in his post would be the best diagnostics for the reverse. It appears you're using an Intel QX5 microscope to take the pictures. If so, try this: Turn off the light in the scope, change the image capture mode from color to grayscale (reduces noise, increases clarity), and use a small hand-held flashlight to illuminate the coin, moving it around so you can get the details you want to see. You may be surprised at the results you can get.

Let's make sure it's a D1 (17 berries, scratched top arrowhead) reverse and not a D2 with some similar markers. The thing that your right blue arrow is pointing to is actually a deceiving raised triangle of metal present on all 1921 dollars.

Thanks John, I will try that when I get home tonight. I will also look into the other diags that you have posted.
