Nice example with a very crisp strike. I've seen them anywhere from $50 to $150. Finding them on the 1-cent denominations is a bit tougher, as is finding the version with 1870 date instead of 1866; I'm still looking for a nice example of the 1870.
The toughest Walker & Taylor cancel (and also my favorite) by far is the 7-line version that was configured for the slightly larger 4-cent denomination. I've only ever seen one example, and it's the one I bought from Richard Friedberg (and paid crazy money for). I use it as one of the images on my business card. What I like about it is the mention of "Extract of Fireweed" which sounds like something out of Harry Potter.
