I have seen comparable examples of other quarters upon which there is some debate about whether it is caused by PMD or a true error or improperly annealed or something else. The edge seems completely normal to me. I haven't seen this color on this particular Ozark Riverways Missouri which is highly detailed and picturesque. I found the Utah quarter pictured below online was described as "gun metal" color and that's how I'd describe mine as well. Report this Post to the Staff

Spence Moderator United States 34410 Posts	Posted 03/30/2023 07:23 am Yes for sure some debate on this. My personal opinion is that odd coloration should be assumed to be from chemical/environmental exposure rather than improper heat treatment by the mint.

ijn1944 Bedrock of the Community United States 19155 Posts	Posted 03/30/2023 07:59 am I'm thinking the 2017 D quarter spent a little time in a poorly maintained fountain or in contact with mostly moist soil. Environmental discoloration is my guess. Report this Post to the Staff
