Hello all, new to stamp collecting. Need help knowing the exact errors of these stamps, and their true description. please and thank you.

You might want to point out what you think are the errors. These look perfectly ordinary.

The Liberia block has a bad registration of the colours. It is a variety at best. It is cancelled to order: philatelic that most collectors avoid.

I was told on the single stamp the 22 cents value printed on the $2 stamp instead of the $2 value. I was told the block of 4 is impref. Between Vertically, cancel to order, 13 dots in top ark, yellow color missregistered. I have a singke stamp of the 4 block that does not have the 13 dots. I can't seem to find these anywhere and no one can seem to help. Everyone gives me a different answer. I was told to come here that the experts would help out. I need to know what these are so I can discribe themand want to know if they are worth it. I have billions of stamps and Philatelic items a whole room full from top to bottom. Please and thank you for your time.
