The short answer is: No.
The bit longer answer is that you minimally need is a reference library of: 1. Literature (knowledge) 2. Images of known genuine to compare against. (or stamps themselves, but that is typically not feasible)
You can get high resolution images of certified material from several auction sites.
Thanks for your post, Henry (henrye ). I would encourage you to include images with your posts, as it always gives members more to go on when trying to respond.
You did an exemplary job of that on the Bavaria gray-color 20-pfennig issue, and it really made the discussion get rolling. If you are able to provide some examples of the stamps you are concerned about, it will give some great visual context to your question.
henrye here is a link to a Hamburg stamp with a cancellation similar to your first stamp (although not the same denomination). There are a number of stamps on e-Bay, some having certificates (which may not be conclusive as fake certificates have been known of)

Thanks for the link, Stan. I did actually see that one when I searched ebay. In fact, I found the same 9s stamp as mine, for sale with an almost identical cancel as mine, on ebay about 6 months ago. This prompted me to list it for sale.
I especially like the 224. (Actually, they both look good. LOL)
How do you get stamp images to turn out like this? Trying to bring out more detail, I've edited stamp images with photoshop but have never gotten this intense of a contrast between a stamp and the cancellation mark.
Looking at the the last two images you posted is interesting.
Especially when you get the negative image. the 424 is odd. In the negative, it looks as if the 2 has a 'shadow'.
It makes me wonder if some of the ones that are supposed to be fake, may not be. What if a postmaster had to recut or otherwise repair his/her cancellation stamper? There would be little to no consistancy and we would even see some that looked downright sloppy. Being a good postmaster was probably more important than the ability to make/alter/repair a cancellation stamper.
Were the cancellation stampers made of wood or metal? I was envisioning a postmaster touching up or repairing one. Back then a replacement might have taken time. Although they probably did have spares.
