2026 Reverse Proof Peace Silver Dollar. The first one I received from the US Mint appeared to have a smudged fingerprint on the bright cheek & neck. It was hard to see, but something seemed amiss. I have other reverse proofs without such a discrepancy. I exchanged it for a replacement. This one appeared, with the naked eye or a magnifier, to have a spec of dust on the inside of the plastic or on the coin itself. Can't tell. From the attached photo, see inside the red circle. That looks more like a divot in the metal. Hate to return it again even though it's a bit bothersome. Is this considered acceptable for a $173 US Mint proof coin? Thanks.
