I like me a good fancy or large-format embossed cancel, especially if well struck. While some collectors eschew them because they damage the stamp, I think the overall aesthetic appeal outweighs what it does to the stamp, especially if the stamp is of nominal value to begin with. On a several hundred dollar or higher catalog value stamp, that's potentially a different matter.
This 1875 bank check has a lovely embossed cancel from Robert Fitton in Cavendish, Vermont, "Manufacturer of Woolen Fancy Cassimeres". The word "cassimeres" is an archaic spelling of cashmere.
