Procedures For Identifying A New Discovery

Let's look at my procedure when encountering a potential new discovery
I find something different, odd, out of place...call it what you will, it's an anomaly.

In the photo is a 2017-P Ellis Island Quarter, lightly circulated, found in a mixed bank roll. This specimen has extra metal below Mr Ellis' chin, behind his head, under his nose, and in front of his eyebrow. Ellis Jr has a bit of extra metal between his lips, reminiscent of Class 8 DDR's around the Lincoln statue plus a possible bit above his thumb.

FIRST: Is it Damage?
The most common misdiagnosis for an anomaly is damage. Always assume damage, them prove otherwise.

This does not appear to be damage.

NEXT: Compare to a similar coin.
This provides a reference against which I can examine differences. Hopefully the reference I am using is a normal coin. This is a great reason to build a complete set.

Ask: Is it Machine doubling?
After damage, md is the next most confused issue.
This is not consistent with md.
Ask: Is it the result of die wear/die deterioration? No

Ask: Is it clash marks? No

I've eliminated the most common explanations.

From here I go on a binge, checking for known varieties on Wexler and Variety Vista. If none are found, the coin may be a new discovery. It may also be an incorrect diagnosis of doubling, but my experience says keep going.

I can set this aside, hunt for another just like it. This could take forever and may never happen.
I can set it aside and wait for someone else to find one. They would receive the credit for the discovery.
I can offer photos and see what other people have to say.
I can send it to be attributed. I risk a few bucks, but if I'm right I get credit for the discovery - a fine feather in one's cap.

This procedure employs deductive reasoning to eliminate known possibilities and compares the anomaly to a control.

There is science behind the madness, even if its still madness.
