Washington Quarter. No Year Grease Shot?

Looks like a nice Greaser. 2x2 worthy.

If the weight is normal. Struck Through Grease it is. Thanks, Doug.

Not sure if I'm thinking or wishing you need a minimum 50 or more posts before opening this can of worms.

In the archives, Some of the top experts have gone head to head on this matter. I found legitimacy on both sides of the fence. That's one reason I try and rule out the weight prior, then move on.


I'm sure it's subject to change, but thus far the only cameras I've heard mentioned are watching the employees and or facilities, not so much the individual coin production itself. Thanks, Doug.

wasl51, Hope you know I was joking around somewhat. The experts may add more to your inquiry in a bit. Since I'm still on the fence I feel its best to keep my Two Cents to myself. Thanks, Doug.

A Adjustment Strike is not even close to being the same thing. It's a different animal. If it was an Adjustment Strike, the rims wouldn't be present. What you have here is a Struck Through Grease error. Here's a link on the differences between the two. http://www.error-ref.com/weak_strik...rampressure/ http://www.error-ref.com/struck-thr...-grease-oil/

So Errers, are they worth anything?

Observe error-ref weak strike description closer. The animals can be somewhat similar. This example is slightly under weight, but within +/- 0.227 clad tolerance. http://www.error-ref.com/weak_strik...rampressure/


One way of thinking is a fully developed rims equates to proper strike pressure being applied and presume grease filled die(s). A fresh stuck though layer of grease is easily detected as it leaves a smear on the coins surface, but will disappear over time. Other than the missing device(s) themselves, the devices compacted with debris and grease leave little other evidence.

Another way of thinking is the design rim is one of the first things to fully fill. The devices, including the rim gutter rely on the material backfilling in response to contacting the collar. So weak devices from lack of pressure are possible with seemingly fully developed rims present.

In my mind the effect either way, would be similar in appearance. Some larger areas or die recesses can be resource hogs and show weakness on the coins opposite side as well.

Now I'll add weight into the mix. I've seen slightly under weight planchets strike up a seemingly decent rim, yet display weak devices. This one is easy to rule out with a scale, but often presumed to be Grease Filled Die. Here's where taking logic over perception may eliminate one or the other.

A few of the main ingredients for a decent strike are, consistent pressure, consistent weight, consistent containment and a consistent design pattern.

To answer my own follow up question, Yes, any combination of above or all the above can be present at the same time. Thanks, Doug.
