A stingy sort of request, you would be well advised to flesh out exactly what you are after.
I like them, would have value to me.
First one : Postmark unknown
Second one DOLGELLAU Merionethshire (Formerly Dolgelly Wales) Pmk 222
228 Miles North west of Londinium
West of the Cambriam Mountains
Third is Mutilated Stationery piece, from an envelope dated 15th March 1880.
This is a privately produced envelope by WH Smith and son
and referred to as a "Collared stamp" due to the advertising ring.
Not much $ value as advised but collecting and study value.
