Help Cassification Stamps Washington

it is really difficult to classify them, I tried but without useful result, could you give me a hand?
I would be very grateful, greetings Simone

Hi Pisti,
You've bunched a lot of them here together.
I would suggest, posting this with:
2 cents as one message
3 cents as one message
Others as one message is ok.

BUT...
You need to know water marks on these in almost every case to get a definitive result. You should also start with a perforation gauge. (Do you have one?)
It would be best for the 2 and 3 cents, we need stronger images to be able to accurately type them. So we need high resolution images, either scan or photo at a big resolution.

Happy to help you sort your WFs, but need you to help me help you.
