Test Strike

Are you referring to a die adjustment (low pressure) strike?
This looks like a grease-filled die. Here are some examples of abnormally weak strikes: http://www.error-ref.com/weak_strik...rampressure/

Referring to the missing letters..
It's not a Struck Through Grease coin..
The lighting maybe causing that effect.

I do not have a die adjustment for US coins but I can put for example of those test coins a Canadian Quarter.

Struck Through Grease issue. Not the devices on America? Note that the affected ones that are there are wider because the grease prevented the forming of the narrow parts of the devices.

The examples to me look like they were plated? I wonder if this is a lower pressure issue, but didn't look good, and they plated the coin to cover the ugly? Note the areas where it looked like something was plated over and now crumbling with power on some areas?

No this coin it is a legitim one. My photos are to shiny. I was involved in adjustment and they permitted me to have the first test strike. I will keep for me because I thing it is not a legitim collecting coin. I keep just for example.

Try a different angle of light. That might help:

I take another photos. This was the first strike at 50 tones. Those coins in Canada are core zinc then nickel, copper and nickel platted. Mean 10 micron Ni. 15 micron Cu and 5 micron Ni

I've heard that Canada Used to plate their dies to make them last longer? When the plating peels off the die, then is leaves a raised area where the plating on the die is missing.

Is true. They powder plated the majority of the dies with iridium. This it is a cause we find in lab that can make the silver or nickel plated coins to become gold light yellow color. We find that those coins have Ir oxide. It is not a stone yet but must be studies more.

we find Ir3S
