2019 Washington Quarter, Some Kind Of Error Or Just Damage?

An accurate weight (out to two decimal places) might tell us more about what may be happening with this coin. An end-on shot of the rim would be helpful too. Thanks.

The devices along the perimeter on the reverse are partially or completely missing--including GUAM, EPU and WAR IN THE PACIFIC.

Yes quite interesting with the reverse devices missing around the entire perimeter as mentioned but also the date looks struck a bit higher (although I didnt adjust the slight rotation of the image) which hints at more going on than a Struck Through Grease for example.

Seems similar to:

This 2008-P Andrew Jackson dollar coin did not receive a full strike. Insufficient ram pressure (applied tonnage) or insufficient die approximation are the culprit in this case. This error is often erroneously called "a die adjustment strike". (Weak strike).



Weak strikes are sometimes confused with grease strikes - coins that are struck through a heavy layer of compacted die fill. It's actually quite easy to tell the two errors apart.

A weak strike will show a poorly developed or absent design rim. A grease strike will show a very well-developed design rim.
A weak strike will retain some, most, or all of the planchet's original proto-rim. The proto-rim is erased in a grease strike.
A weak strike will retain the beveled rim/edge junction of the planchet. The bevel will be lost in a grease strike.
The edge will be weakly struck and relatively narrow in a weak strike. The edge will be tall and vertical in a grease strike.
Reeding will be weak or absent in a weak strike. Reeding will be very strong in a grease strike.
In a weak strike, extent and pattern of weakness will be essentially the same on both faces. Uneven weakness is a hallmark of most grease strikes. https://www.error-ref.com/?s=weak+strike

Heres the reverse, I mentioned it only because it reminded me of that look of the missing devices around the entire perimeter. But a weak strike is mentioned as above says "In a weak strike, extent and pattern of weakness will be essentially the same on both faces" which is why I said similar to instead since it mentions both sides.

Might need coops and Mikes input on this.

1. Well it can't be a Grease Fill issue, as the devices are raised on the die. (incuse on the coin)
2. Weight might help. If the planchet was thin or altered, it would be under in weight:

5.67 grams would be normal weight with a tolerance of +/- .19 grams. So an accurate weight would be helpful.
3. I'm seeing an disturbance on obverse on the planchet near the rim area, that is also seen on the reverse partly.Which makes me think it was damage post strike. (Note how just the upper part of the date is showing? The lower part is missing and a line is present there. (Which says to me that it could be an altered coin issue.
4. Are the reeds showing on the outside edge of the coin? Can't tell on the images provided.
5. Is the outside diameter same as another coin, or larger?
So these answers to these question will help Mike Diamond when he checks. Just the first time for me to see anything like this. So when we get these answers, we can call Mike in on this one.
