Parking Lot Ike: Legitimate Mint Error or Bizarre PMD? (Help Needed!)

Hello everyone! This is my first post here. I just joined today and have already found a ton of useful information roaming around these forums.

I recently found an Roosevelt dime in, of all places, a convenience store parking lot. I almost walked right past it, but I’m glad I stopped to pick it up because it’s incredibly interesting.

At first glance, I assumed someone had intentionally damaged the coin with a vise or a shop press. However, the reverse is completely flat and entirely free of the kind of distortion or flattening that a heavy press would leave behind.

On the obverse, there is a distinct, raised circular area. Right inside this raised section, you can see Roosevelt's ear almost perfectly preserved. The metal in this specific raised area is smooth and shiny.

I'm trying to figure out if I stumbled onto a rare mint error or if this is just a highly unusual form of Post-Mint Damage (PMD) that I can't quite reverse-engineer.

I would love to get some insight from the error experts here. Any advice or theories on how this happened would be greatly appreciated!

Thank you all in advance for your time and expertise!

Hhhmmmm.... I'll await the error pros to render judgment. Just be aware the president rendered here is Roosevelt. Not Eisenhower.

 

I was gonna say that it looked like a shim for a kitchen chair leg, but I see no wear on the reverse. Maybe still a shim of some sort.

 

I'm going with PMD. Nothing in the minting process would do this.
Based on the scratches on the side of the "dome-like" structure. Maybe shim as described.

 

That is President Franklin Delano Roosevelt

Hello Brad,
Your Roosevelt Dime is what I call DEFDAM - Definitely Damaged
It was altered after it left the US Mint. It is not a known Mint Error of any kind unfortunately.

Only the person who deliberately damaged it would know how it was done.

How do I know this? I have 40+ years of collecting, studying and attributing true mint errors.

Me and many other knowledgeable members on the topic of error coins are here to help.
So welcome to CoinTalk!

 

Yes! I feel like a goof.. Roosevelt grrr

 

Thank you for the warm welcome and knowledgeable reply. Now that many have said shim, that makes total sense. I appreciate the help

 

Yeah that makes a lot of sense. Appreciate the repy!
