Error CUD | 1971 is this is a cud?

[loquixx]

[Roller]

No it is not a cud. It looks incuse. If it is, it may be due to a die subsidence.

[VAB2013]

I agree with Roller, it's not a cud, but to me the area looks raised with a small circular portion in the center that looks incuse. But it does not look raised at the rim the way a cud would be. What does the reverse look like? Maybe it's just me, but that's what I see.

[Petespockets55]

No, not a cud.
A cud will be on the rim of the coin and be raised from the surface of the coin.
Simply put a piece of the die has broken away and no longer holds the metal of the blank planchet in place during the strike. The metal of the planchet flows into the area of the missing metal on the die and voila... a cud is created.

That is cool looking... Looks in-relief to me so I am on the die subsidence band wagon - From our Glossary

Die Subsidence (sunken die): An error where a portion of the die face sinks into the die resulting in a raised portion on one face of the coins it strikes, and often exhibits weakness of strike of the opposite side. The most well-known instance in the Lincoln series is on a 1924S, commonly known as the “goiter” cent.

Correct Jim. I had the mirror image backwards. I.e. if "raised" not "incuse".

[enamel7]

Looks like a stain to me.

[GrumpyEd]

It might be something like clear glue that got there after the coin was already toned so you see the normal color through it.

[Petespockets55]

Can you tell us if the area in question is sunken into the coins surface or raised above the surface?

[loquixx]

raised above the surface

[Petespockets55]

raised above the surface

Thanks.
My brain was doing the inverted optical trick again making it look recessed.

[Roller]

raised above the surface

Have you soaked it in acetone? The observation that it may be glue raises a substantial challenge to the subsidence theory.

[VAB2013]

raised above the surface

Okay, the pic that I could tell the best that it looks raised is the third photo down. Please let us know if it changes any after soaking in acetone, that will let us know if it's glue or something else stuck to the surface of it.

I did too at first... Good thing I reread my sentence before submitting
