It looks like little drops (or blobs) of metal on the leaf, above eye, on nose, and chin.

Welcome and nice images.
The eyebrow and chin appear to be die chips and the spot above the leaf looks to be what is referred to as a die dot.

The chips can form in conjunction with die cracks or all by themselves. Basically it is a small area of weakness in the surface of the die that comes out for different reasons and causes a small void in the face of the die (die age, fatigue, over use,etc). Once the metal that forms the die chip is gone, any planchets struck by the die will flow into the void and appear as an extra bump.
They are interesting to find but don't generally have any extra premium unless it is extreme.

A die dot is usually smoother around the edges and is usually formed by something (sand, grit, etc) causing a small impression into the surface of the die.

Edit: I forgot to mention that both will be in relief as opposed to incuse (recessed) on the coin surface. Most of the time, but not always, an incuse element on the coins surface is a sign of PSD.

Thank you so much for the clear information. I have been reading up on errors but without a description that gives an example picture, it is hard to understand.
