Hi everyone,

I'm new to the forum — you can call me OklaNumist. I collect mostly U.S. coins found through circulation and estate lots here in Oklahoma, and I recently came across what looks like an interesting 1971-D Eisenhower (acne and ear wax) dollar.

What I'm Seeing:

Obverse (front): Golden, blotchy "acne-like" patches on Eisenhower's cheek, jaw, and ear. Under magnification they appear within the metal — not corrosion or gunk.

Reverse (back): Similar gold-brown discoloration and rough texture across the eagle's wings and body, almost like peeling or flaking of the clad layer.

Other checks:
Non-magnetic
Normal weight (~22.6 g)

Stored uncleaned in a capsule

From what I've read on Error-Ref.com and CONECA, this might be a planchet lamination or improper alloy bond common to early 1971-D Ike dollars, but this one shows coverage on both sides — which seems less typical.

Looking for Input:

Does this look like a genuine lamination / delamination error to you?

Does two-side coverage add any extra collector value?

Would this be worth sending to NGC or PCGS under the Mint Error tier?

I've attached full obverse/reverse photos and close-ups of the cheek, ear, and eagle wings. I can post edge photos or different lighting if helpful. I have made close and zoom out recordings as I shifted the light if interested.

Thanks for taking a look — I'm eager to learn from those who've handled Ike errors before.

To CCF! It looks like staining to me. If it is, it's PMD and only worth face value. Not worth slabbing either way.

to the CCF, OklaNumist.
I agree with Errers - it looks like staining or gunk. Try soaking it in 100% acetone overnight to see if the discoloration persists.

Thank you for the welcomes and feedback. Everything seems to point to "don't clean!!" so I was leery, however I have 100% acetone now.

Can you point out some good reliable information on cleaning coins of different compositions?

OklaNumist, start with Bad Thad's Polarity Ladder: https://goccf.com/t/57008#447106
Water, acetone, and xylene will not affect the metal of coins. Anything that removes metal - acids, etc. - must never be used on coins.
After these solvents have removed soluble contaminants, coins can be treated with VERDI-CARE™.

Thank you, I stored the info. I got more cleaning question, however I am going to try to find the appropiate thread.
