I agree with translateltd and I think it's no coincidence that the bubbles and the A are close together (I think I see a similar flattening on the I above, with more bubbles near by).

My scenario would be a die that had just been cleaned, but some of the cleaning agent was not removed. As the coin was struck, the letters appeared flattened. The coin passed quality control and was packaged in a roll. Here, the acids in the remaining cleaning agent started to react with the metal, hence the bubbles. Mind hat this s speculation, but it fits the facts.
