Surely nothing that a cup of tea, a Bex and a good lie down won't fix.

There are dings in her eyebrow and forehead, which helps to suggest she is frowning. Maybe DID have a headache, sometime in 1971.

Lamination error, was more common around this date period.

Lamination errors are the result of minor impurities in the blanking strip, which spread out within the strip when it is rolled to thickness.
It's a bit like putting a soft blob of butter between two slices of bread, and rolling those together with a rolling pin. The butter spreads out between them.

Lamination errors can express themselves in two ways:
1. Surface peeling, as you see here, and
2. Complete flan splitting, which in the worst cases, results in the coin splitting into halves, each half carrying a complete obverse or reverse design.
