Hello, everyone!
I need some help identifying some flaws. I would like to know if the flaws indicated in blue on the attached stamps may be some variation/error listed in a specialized catalog. I identify the stamps as SG 47, 86, and 87.
Any comments would be helpful.


In this one, the number seems to be melting

In this, the word 'HALF' looks like 'HAL,F'
