Coinbuf Posted June 13, 2022 Posted June 13, 2022 It is PMD, there are a few ways for that to happen, a weak acid like pool acid can do that and recently Mr. Lange posted that long term emersion in a sonic jewelry cleaner can produce this same effect.
Patman54 Posted June 13, 2022 Author Posted June 13, 2022 Curious though how it only effects one side? If it was submerged long enough to do that I would think it would be on both sides.

Oldhoopster Posted June 13, 2022 Posted June 13, 2022 Hitting it with a wire brush will give a similar effect depending on wire type/gauge and speed
Patman54 Posted June 13, 2022 Author Posted June 13, 2022 Wouldn't that leave brush marks and scratches I would think

Im sure if you brushed it long enough, the design and waviness would disappear
