U.S. Quarter with a Smooth Edge — Possible Mint Error? Weight and Comparison Included

Fanjun

Hello everyone,

I have a U.S. quarter with an unusual edge that appears to be missing the normal reeded pattern.

I would appreciate the opinions of experienced collectors on whether this could be a genuine mint error or post-mint damage.

To help with the evaluation, I will include the following photographs and measurements:

1. Obverse (front) of the coin.
2. Reverse (back) of the coin.
3. Close-up photographs of the coin's edge.
4. The coin's weight measured on a scale.
5. Side-by-side comparison with a normal U.S. quarter, including the edges.

I have examined the coin and do not believe the edge was intentionally ground down or filed. However, I understand that photographs and measurements alone may not be enough to determine whether it is a genuine mint error.

My questions are:

1. What type of minting error, if any, could explain this smooth edge?
2. What details should I look for to distinguish a genuine mint error from post-mint damage?
3. Could the coin have collectible value if it is confirmed to be a genuine mint error?
4. Would professional authentication be worthwhile in this case?

I would appreciate any observations, opinions, or suggestions.

Thank you for your time and help!
