French cancels - 01 l Paris numbered stars (étoiles chiffrées) - variations 5

For this post, I present the last (so far) known variations on the star cancels.
 

Variations on the 23:

For this specific cancel all 6 points of the cancel are gone, as if the cancel started to melt.
Incomplete cancels (on the stamp alone) can create the illusion of an incomplete cancel.
Therefore only clear cancels or cancels on letters can tell if the 23 is a normal cancel or a truncated one.

étoile 23 tronquée (truncated)

Variations on the 28:

This variation is clearly due to the use of a worn out  hand cancel.
The degeneration of the cancels made the 28 look like a 20 in the end...

normal 28 - cancel

28 second state

28 third (laste) stage

For cancels in this last stage, some expertise is needed.
Lack of ink, or soft cancels can create a 28 in this third state. Not even mentioning the removal of the centre by fraud.
