Fake Cancel?

A good general rule of thumb with fake cancels is to always suspect any stamp worth more used than mint. This is often the case with older high value British Colonial stamps.

Bear in mind that a £1 stamp of the George V era would represent around 100 times the basic letter rate, and you can see that usage would be pretty limited. If one was used, the post office workers would have been instructed to make sure that it was pretty thoroughly cancelled, and there was no danger of it being reused.

The vague, blurry corner cancel, in which the place name and date are illegible should also ring alarm bells. It's easy enough to make up an all-purpose cancellation like that. A stamp with this sort of cancellation might be perfectly OK of course, but why take the risk?

Doesn't some countrys for the stamp trade sell pre-canceled stamps? They look like they are canceled but if you get 2 or more together the cancel and placement is in the same spot.

Given the list that Litho provided has anyone searched their stamps for any of the forged cancels? My interest was the German Baden cancels such as Rastat and Freiberg. I'm shocked that there hasn't already been some fake cancels posted here based on that list.
